Random white screen with SwingTerminal #2

Open GoogleCodeExporter opened 9 years ago

GoogleCodeExporter commented 9 years ago 
On Ubuntu 10.04, sometimes when launching the SwingTerminal, the window starts 
all white and it doesn't draw anything. Seems very random, still haven't been 
able to figure out to reproduce it.

Unverified on any other platform

Can't reproduce

The problem still there somewhere,it happend to me on my windows(Windows 7 
Ultimate) box,i have not tested it on my linux box yet.

SwingTerminal seems to fail loading or something,after it happends i just use 
to re-rerun it and it usually doesn't happen again,its very random.  :(

Ok, let's re-open this. I haven't seen it happen for a while, I think I did 
something a while back which made it go away. Let's keep our eyes open and put 
anything that may be related here...

It's a pity.

This problem makes the program unstable.

This hasn't happened to me in a long time now, anyone who's seen it recently?

Yes me, many times per day.

About, one in Ten.
I'm obliged to kill swing terminal and relaunch my software.

I'm on Debian 64bits in Gnome-Shell 3.4

GoogleCodeExporter commented 9 years ago 
Okay, could you please make a minimal example that reproduces this behavior and 
post it here? I still can't get it to trigger on my side...

I've tried it 20 times on XFCE but still no problem. Will try to find a Gnome 
installation somewhere to try on; it may be related to desktop compositing.

I'm seeing the same issue, too. As far as I can tell, just starting and 
stopping the Screen seems to be enough:

    SwingTerminal terminal = new SwingTerminal(80, 25);
    Screen screen = new Screen(terminal);
    screen.startScreen();
    screen.stopScreen();

As mentioned previously in the thread, it's rather erratic. Sometimes it 
happens immediately, other times it takes several attempts. I'm running Fedora 
18 with stock Gnome shell and Ubuntu 13.04 with Cinnamon (which uses Gnome 3 
under the hood).

This is a minimal example that exposes the issue:

    import com.googlecode.lanterna.terminal.swing.SwingTerminal;
    import com.googlecode.lanterna.screen.Screen;

    class Main {
        public static void main(String[] args) {
            SwingTerminal terminal = new SwingTerminal(80, 25);
            Screen screen = new Screen(terminal);
            screen.startScreen();
            screen.stopScreen();
        }
    }

The following shell script usually triggers it within a minute:

    #!/bin/bash

    while true; do
        java -cp .:lanterna-2.1.5.jar Main
    done

The result is always the same: the program doesn't exit and the window just 
hangs there, empty with white background. It doesn't response to any input and 
the only way to shut it down is to `kill -9` the Java process. There is no 
output on STDOUT or STDERR.

Since it takes some time to trigger the issue (due to the JVM startup time), I 
tried to wrap the `Main` body in an infinite `while` loop.

Then I actually get a stacktrace printed out:

Exception in thread "AWT-EventQueue-0" java.lang.NullPointerException

    at java.awt.EventDispatchThread.run(EventDispatchThread.java:91)

Again, this doesn't happen every time -- more like 1 out of 10 times the 
`while` body is executed. But this time, the program doesn't freeze, it just 
continues with the loop (i.e. the Swing window isn't left hanging).

I wonder if this is the root of the issue somehow getting swallowed by the 
Swing machinery, rendering the process unresponsive. But I know very little 
about how Swing works so I've no idea whether this is useful or misleading.

I've just tried it under XFCE and the issue is there, too.

After looking into this some more (I compiled the latest source) it seems that 
the exception is probably unrelated to the hanging.

Sometimes `frame.getGraphics()` returns `null` at the following line:

https://code.google.com/p/lanterna/source/browse/src/main/java/com/googlecode/la
nterna/terminal/swing/SwingTerminal.java#445

That caused the exception, so I added a check that returns if there's a 
`frame.getGraphics()` is null. That took care of the exception but it didn't 
solve the hanging.

Thanks to Advanced Debugging Techniques (i.e. System.out.println) it seems that 
the hanging always occurs when calling `terminalFrame.setVisible(false)` in 
`SwingTerminal.exitPrivateMode`:

https://code.google.com/p/lanterna/source/browse/src/main/java/com/googlecode/la
nterna/terminal/swing/SwingTerminal.java#221

I tried to look around a bit but I'm really out of depth when it comes to 
Swing. It seems that this tends to occur when you manipulate the JFrame's 
visibility from a thread other than Event-Dispatch.

Calling `javax.swing.SwingUtilities.isEventDispatchThread()` returned `false` 
so that would seem to support the hypothesis. However, the commonly-quoted 
solution (running the setVisible code inside `SwingUtilities.invokeLater(new 
Runnable() { ... })`) didn't work for me. Maybe there's some other offending 
code, or maybe it's something completely different -- I don't know.

Hopefully this helps to at least narrow it down a bit more.

Let me try to sample code above again and try...

I've deployed a new 2.1.6 snapshot, wrapping a little bit more code in 
SwingUtilities.invokeLater, but I'm not convinced it will be enough. So far I 
haven't been able to reproduce the issue with the code above, I let the script 
run for a good 15 minutes...

What version of Java are you using? What happens if you try to run jstack on 
the process when it's broken?

Using lanterna-2.1.6-20130627.005818-4.jar, I got the hang again.

So there's a deadlock between AWT-XAWT and AWT-EventQueue-0... Googling around 
a bit shows that it seems to have been reported to Oracle, but they too have 
problems reproducing it. 

Just for curiosity's sake, could you try with an Oracle JDK/JRE instead of 
OpenJDK?

Sorry for the delay. I've tried the Oracle JDK and it hangs, too.

$ java -version
java version "1.7.0_25"
Java(TM) SE Runtime Environment (build 1.7.0_25-b15)
Java HotSpot(TM) 64-Bit Server VM (build 23.25-b01, mixed mode)

The jstack output looks very similar, I've attached on the off-chance it might 
help.

It's definitely the same issue they are having here: 
https://forums.oracle.com/thread/2244637

There seems to have been a bug report with Sun/Oracle but it seems to have gone 
missing:

I'm curious if the new SwingTerminal in lanterna 3 fixes this issue...
