Eclipse crashes in Webkit code

[heike2718]

Describe the bug Eclipse crashes frequently and unpredictably under Debian 10.

To Reproduce The error could not be reproduced reliably so far. But it is possibly connected with the clipboard: when I cache text to the clipboard from another application (terminal,...) and try to paste it into the Eclipse editor the IDE crashes very often.

Expected behavior No sudden crashes any more.

Screenshots

Environment:

• Select the platforms on which the behavior is seen. [] All OS [ ] Windows [X ] Linux [ ] macOS

never faced it on Windows

• Additional OS info (e.g. OS version, Linux Desktop, etc)

Operating System: Debian GNU/Linux 10 (buster) Kernel: Linux 4.19.0-20-amd64

• JRE/JDK version OpenJDK Runtime Environment (build 11.0.15+10-post-Debian-1deb10u1)

Version since Not sure: it started with

Eclipse IDE for Java Developers (includes Incubating components) Version: 2021-12 (4.22.0) Build id: 20211202-1639 OS: Linux, v.4.19.0-20-amd64, x86_64 / gtk 3.24.5, WebKit 2.36.0 Java vendor: Eclipse Adoptium Java runtime version: 17.0.1+12 Java version: 17.0.1

but not immediately after upgrading to this version and remained after an upgrade to 2022-03. Actual Eclipse Version:

Eclipse IDE for Java Developers (includes Incubating components) Version: 2022-03 (4.23.0) Build id: 20220310-1457 OS: Linux, v.4.19.0-20-amd64, x86_64 / gtk 3.24.5 Java vendor: Eclipse Adoptium Java runtime version: 17.0.2+8 Java version: 17.0.2

Workaround (or) Additional context Starting eclipse with the command line option -Djdk.gtk.version=2 did not help. Tryed this because of a hinf from another forum about possible incomatibilities between gtk3 and eclipse.

*** Security Configuration:

[heike2718]

The crashes may be related to the cache / clipboard. They seem to occur more often when I have just cached texts from another application (Ctrl + C) or have not yet cleared the cache.

The interaction between Eclipse and the clipboard is quite unstable overall. Sometimes the IDE freezes when I have texts in the cache, so I have to empty it first.

The instability has been like this for several versions, but with the latest version the described crashes are added.

[sxc731]

This issue also occurs on Ubuntu 22.04 (Wayland); everything is up-to-date as of this writing. I've had three occurrences over the last couple of days, with:

# Problematic frame:
# C  [libwebkit2gtk-4.0.so.37+0xbc79e6]

For me, this typically occurs when hitting CTRL+Space in order to auto-complete some stuff, eg: in a Javadoc comment is the one that occurred most recently. Let me know how I can further assist in debugging this?

Some version info:

Eclipse IDE for Java Developers (includes Incubating components)
Version: 2022-03 (4.23.0)
Build id: 20220310-1457

openjdk 17.0.3 2022-04-19
OpenJDK Runtime Environment (build 17.0.3+7-Ubuntu-0ubuntu0.22.04.1)
OpenJDK 64-Bit Server VM (build 17.0.3+7-Ubuntu-0ubuntu0.22.04.1, mixed mode, sharing)

libwebkit2gtk-4.0-37:
  Installed: 2.36.3-0ubuntu0.22.04.1

Perhaps change the title of the ticket to reflect this doesn't only happen on Debian?

[iloveeclipse]

@sxc731 : please attach full crash log. If you enable core dumps, you can open core file with gdb and print backtrace via "bt", this would be also good to have.

[heike2718]

@sxc731

you are right. There are 2 different actions triggering the crashes several times a day:

• using the clipboard between applications (it seems not to trigger when using the clipboard only fom eclipse to eclipse)
• using auto-completion

So this is hopefully reproduceable.

[sxc731]

I have attempted to open the crash file and print a backtrace as requested. I don't think I'm getting anything too useful (due to lack of debug symbols?). Below is an edited excerpt. The crash file is 318MB; I'm happy to upload it if it might actually be of any use; please confirm?

[iloveeclipse]

Can you please attach crash dump file generated by JVM (not the core file)?

[sxc731]

Here's one; I have a couple more in case that helps: hs_err_pid30699.log.

Also, FWIW security patches were recently issued for libwebkit and it is quite possible that this coincides with the beginning of these issues; some of these patches certainly caused issues with other software. However, I can't say for sure because I also happened to upgrade my OS (Ubuntu 21.10->22.04) around the same time.

[sxc731]

Got a little bit more lucky with bt this time. This was again a crash triggered by invoking auto-complete.

This happened a minute or so after I saw the weird striped screen mentioned here. Unlike the crash (which is thankfully not too easily reproduced), the striped screen can be readily triggered by invoking an in-line refactor/rename (ALT+SHIFT+R) and it seems possible as mentioned on the other ticket that this destabilizes Eclipse (?)

I tried to reproduce on my Ubuntu 22.04, but I didn't encounter anything suspicious. I also tried a native memory checking tool (finds buffer overruns, double frees, etc) - and also didn't find anything.

It would help if you could reproduce crash from https://github.com/eclipse-platform/eclipse.platform.swt/issues/158 and get a backtrace for it. It seems that these two crashes are related.

Also, please install webkit debug infos and get a better backtrace (you could use the latest core dump you obtained):

1. Configure your Ubuntu for debug infos (note: a single multi-line command below):

   $ echo "deb http://ddebs.ubuntu.com $(lsb_release -cs) main restricted universe multiverse
   deb http://ddebs.ubuntu.com $(lsb_release -cs)-updates main restricted universe multiverse
   deb http://ddebs.ubuntu.com $(lsb_release -cs)-proposed main restricted universe multiverse" | \
   sudo tee -a /etc/apt/sources.list.d/ddebs.list

2. Install debug info keyring

   $ sudo apt update
   $ sudo apt install ubuntu-dbgsym-keyring

3. Update once again to get debug info lists

   $ sudo apt update

4. Install webkit debug infos

   $ sudo apt install libwebkit2gtk-4.1-0-dbgsym

[sxc731]

Hi there,

Thanks for the instructions. I haven't gone through the debug libs installation just yet (and actually haven't encountered any crash since my last post) but I notice you're suggesting to install libwebkit2gtk-4.1-0, whereas I currently have libwebkit2gtk-4.0-37 (and I think issues reported here all refer to that version). Could this make a difference?

I have installed 4.1-0 (alongside 4.0-37) and restarted Eclipse. How do I ascertain which version of the .so is being used? I went to Help->About->Installation Details->Configuration and looked for webkit. This shows: org.eclipse.swt.internal.webkitgtk.version=2.36.3 under System properties; both the 4.0 and 4.1 versions of the libwebkit package are at version 2.36.3-0ubuntu0.22.04.1 so this doesn't elucidate. TIA for your insight.

[SyntevoAlex]

How do I ascertain which version of the .so is being used?

$ pmap -p `pgrep java` | grep libwebkit2gtk

I notice you're suggesting to install libwebkit2gtk-4.1-0, whereas I currently have libwebkit2gtk-4.0-37

Right, my bad. I did apt-cache search libwebkit and my eye caught the wrong line. libwebkit2gtk-4.0-37-dbgsym seems to be the right package.

[SyntevoAlex]

Once you install libwebkit2gtk-4.0-37-dbgsym, you should be able to get stack from your latest core dump, there is no need to crash eclipse again. I would still love to get a core dump/backtrace for #158 though.

[akurtakov]

If installing libwebkit2gtk-4.1-0 solves the problem this sounds like the issue lies in the old version which Ubuntu fixed so nothing to be done on SWT side.

[sxc731]

OK so immediately after a cold start, Eclipse doesn't appear to load libwebkit2gtk (I used @SyntevoAlex's pmap command, did a little bit of simple editing and the library wasn't loaded).

Interestingly, after I trigger the striped screen, then I see that Eclipse has several references to /usr/lib/x86_64-linux-gnu/libwebkit2gtk-4.0.so.37.56.7- so, first off, FWIW it uses the 4.0 version, regardless of availability of 4.1 on the system; I assume that's not an issue.

The striped screen, which is 100% reproducible for me, is at the very least a pretty jarring cosmetic bug and possibly a more serious smoking gun, and it does seem to involve libwebkit2gtk per above...

To reproduce the striped screen, I created an empty workspace with the single following class:

public class Test { }

If you select Test and press ALT+SHIFT+R to invoke the in-line rename/refactor, then type Test2 (or whatever), followed by RETURN, you should get to see the striped screen (at least for me, on Ubuntu 22.04 it's 100% reproducible). It doesn't appear for very long in this instance because the refactor is simple so if your workstation is quick, you might miss it. To make it show for longer, introduce a syntax error - eg: add void m() inside the Test class (purposefully leaving out the body and semicolon) - and try rename/refactor again, you should definitely see the striped screen while Eclipse presents a modal dialog per the below screenshot.

I'll let you know if I manage to reproduce the crash with the debug libs.

As for https://github.com/eclipse-platform/eclipse.platform.swt/issues/158, instructions to reproduce suggest clicking "Migrate" on the Welcome screen. I do not have that "Migrate* option (my deployment is a straight up "Java developers") so cannot reproduce.

[SyntevoAlex]

@sxc731 do you have any plugins installed? Can you try removing them?

[vogella]

@sxc731 any HTML link on the welcome screen toolbar, crashes the Eclipse SDK for me using Wayland.

[iloveeclipse]

@sxc731 any HTML link on the welcome screen toolbar, crashes the Eclipse SDK for me using Wayland.

@vogella : so you can follow this: https://github.com/eclipse-platform/eclipse.platform.swt/issues/179#issuecomment-1147420123 to provide additional information?

[SyntevoAlex]

Better yet, please reply to https://github.com/eclipse-platform/eclipse.platform.swt/issues/158#issuecomment-1146483400 and https://github.com/eclipse-platform/eclipse.platform.swt/issues/158#issuecomment-1142873959

[SyntevoAlex]

Not reproducible for me:

I continue to suspect some Eclipse plugin or non-default Ubuntu package.

[SyntevoAlex]

any HTML link on the welcome screen toolbar, crashes the Eclipse SDK for me using Wayland.

Also not reproducible for me in Eclipse 2022-03 on Ubuntu 22.04

[akurtakov]

In the past we had wayland "drawing" problems that happened only with certain video drivers. So that path is worth investigating.

[sxc731]

@sxc731 do you have any plugins installed? Can you try removing them?

I tried a naked "2022-03 Eclipse for Java developers" and can still 100% reproduce the striped screen.

To @akurtakov's point above, my laptop doesn't have fancy graphics: regular Tiger Lake with integrated Intel GPU. That said, since this was also reported here, it's not just me.

I definitely didn't use to have this issue with a combination of Ubuntu 21.10/Eclipse 2021-12/pre security-patch libwebkit2gtk.

The actual crash somehow hasn't re-occured as yet.

[cpfeiffer]

I can reproduce the crash on Ubuntu 22.04 by clicking on a link on the welcome page with

• eclipse-committers-2022-03
• embedded JustJ JRE
• libwebkit2gtk-4.0-37:amd64 in version 2.36.3-0ubuntu0.22.04.1

I cannot reproduce the crash in the same way on Debian Unstable, where libwebkit2gtk-4.0-37 has version 2.36.3-1.

I also could not reproduce the crash on Ubuntu 20.04 with libwebkit2gtk-4.0-37 version 2.36.3-0ubuntu0.20.04.1

I can do further debugging on Ubuntu 22.04 if needed.

[SyntevoAlex]

@cpfeiffer Please follow steps from https://github.com/eclipse-platform/eclipse.platform.swt/issues/158#issuecomment-1142873959

[gietki]

This is critical. It's a bug in webkit2gtk lib I presume? Happens to me as well (open a project, move mouse over to a method name and wait for autocomplete - boom, crash sigsegv).

Edit: using ubuntu 22.04 fully patched (libwebkit2gtk-4.0-37), eclipse 2022-03R

If necessary, I can provide the coredump, but it's > 200 MB 7zipped,

[SyntevoAlex]

Finally, someone provided something useful! Thanks!

Seems to be this bug: https://bugs.webkit.org/show_bug.cgi?id=200856

It mentions hardware acceleration. This hints why it's only seen on some machines and not the others.

[SyntevoAlex]

The old bug was fixed, but then it reappeared as: https://bugs.webkit.org/show_bug.cgi?id=239429

[SyntevoAlex]

After enabling 3D acceleration in my Ubuntu 22.04 VM, the crash is reproducible for me as well.

[SyntevoAlex]

I understand that this is a problem of WebKit (see https://bugs.webkit.org/show_bug.cgi?id=239429) and not a bug in Eclipse.

[gietki]

Yes, thanks for pointing the issue in Webkit, I guess we will have to wait until it is fixed (no one assigned to that issue and priority set to normal). Is there any workaround? @SyntevoAlex you mentioned that when you enabled 3D acceleration, you meant enabling it in VirtualBox? Does anybody know any native (non-VM) workaround?

[SyntevoAlex]

Yes, I'm running Ubuntu in VirtualBox, and I meant that enabling 3D acceleration there caused the crash to occur for me. Bug in WebKit is outside of my work scope, therefore I will not assist with this problem further, sorry.

[cpfeiffer]

Thanks! I guess the workaround would be to switch from Wayland to X11, at the moment.

[heike2718]

@cpfeiffer thanks a lot for your hint. This seems to be a workaround. It saved my day

[xxorax]

Is there a way to disable Webkit hardware acceleration to temporary fix the issue ? Like evolution does.

The easiest way to reproduce it on my side is to go to Preferences > General > Web Browser : it crashes without showing the settings.

[akurtakov]

There is no way to disable hardware acceleration but you can add if you want . Just use an example how ignoreTls is done https://github.com/eclipse-platform/eclipse.platform.swt/blob/master/bundles/org.eclipse.swt/Eclipse%20SWT%20WebKit/gtk/org/eclipse/swt/browser/WebKit.java#L250 and https://github.com/eclipse-platform/eclipse.platform.swt/blob/master/bundles/org.eclipse.swt/Eclipse%20SWT%20WebKit/gtk/org/eclipse/swt/browser/WebKit.java#L680 . I would be happy to review your patch.

[akurtakov]

Would you please try with https://download.eclipse.org/eclipse/downloads/drops4/I20240329-0530/ ? It should workaround the problem for now.
