It seems the only solution at the moment is not to update to safari 4.0.4,
or use the temporary change described by kurka.daniel http://bit.ly/15GsRE
I switched back to safari 4.0.3 with restoring my hole system backup from time machine.

Same problem here: 10.5.8 - update Safari to 4.0.4. I'm using a workaround from

This is a bug in Safari 4.0.4's JavaScriptCore lib. I'm filing a bug there and I'll
see if I can 
find a work around.

Reported by knorton+personal@google.com on 2009-11-13 20:01:16

[dankurka]

I reported the bug and it has been fixed:
http://trac.webkit.org/changeset/50964

That fix will be in Safari 4.0.5 ... but there is actually no solid work around that
I can think of. Daniel's hack will buy you some 
more runtime but it will still be prone to crashes. (They just aren't going to happen
in gcUnprotect ... they'll happen in one of the 
other native functions)

The underlying problem is that JSValueProtect was accidently changed to a no-op, so
there is no way of protecting a JavaScript 
object that we return to the JVM. Even aliasing the value onto the global object won't
work because the APi wrapper gets divorced 
from the actual JSValue.

It is, however, possible to use JavaScriptCore from a WebKit nightly build. I'll put
together some instructions on how to do this.

Reported by knorton+personal@google.com on 2009-11-13 21:28:11

• Status changed: Accepted

[dankurka]

I was able to downgrade back to 4.0.3, see
http://digitalbreed.com/2009/gwt-17x-safari-404-crash - but be aware that this may
have unknown side-effects and may cause a loss of data. Backup your stuff first.

With much gratitude to Matt Mastracci, I'm back up and running with GWT hosted mode
in Eclipse 3.5.1 on 
Mac OS X 10.5.8 Leopard.  The basic steps are here:

http://grack.com/blog/2009/11/16/fix-for-gwt-hosted-mode-crash-with-safari-4-0-4/

I did this:

(1) From http://nightly.webkit.org/, download the current Mac OS X build:
WebKit r51062 was built on 17 November 2009 and is a 35.7 MB download.

(2) Open up the .dmg, then drag it (WebKit) to /Applications/.

(3) In Eclipse, select Run->Run Configurations... from the menu.

(4) On the left side, select your GWT Web Application.

(5) Click the Environment tab.

(6) Add variable:
      Name: DYLD_FRAMEWORK_PATH 
      Value: /Applications/WebKit.app/Contents/Frameworks/10.5

(7) Save that [Append environment to native environment should already be selected].

You should be good to go; this worked for me the first time.  (Kelly, please jump in
if you see any problems 
with this!)

thanks for the succinct summary there jdouglas! :) - worth noting that Snow Leopard
users should set the value

This also helped me, though I'm using Snow Leopard so I used 
Value: /Applications/WebKit.app/Contents/Frameworks/10.6 
and this solved my crashing as well, thank you!

Thanks.  This saved me.  I was a bit surprised that a safari upgrade would bust my
GWT application.  

I also used jdouglas's steps in comment 22.  I have snow leopard so used the
additional tip mentioned by funky.groovemonkey in comment 22.   

So other people can find this error via google I am entering a little of the gwt text

how can I achieve it (because I can't configure a web application launcher) ?

Reported by jerome.cance on 2009-11-23 14:16:44

Instructions for setting environment variables for Leopard (10.5): 

1) edit /etc/launchd.conf to add the line:

setenv DYLD_FRAMEWORK_PATH /Applications/WebKit.app/Contents/Frameworks/10.5

- If the /etc/launch.conf file does not exist. You can create it using the Terminal
application.

a) Open up a Terminal prompt

b) sudo vi /etc/launchd.conf

c) Add the contents to the /etc/launchd.conf file:

setenv DYLD_FRAMEWORK_PATH /Applications/WebKit.app/Contents/Frameworks/10.5

2) Save your changes in Vi (command to save and quit :wq )

3) Reboot your Mac

4) Prove that your variables are working by opening a Terminal window and typing
export and you should see your new variables. These will also be available in
IntelliJ and other GUI apps you launch via Spotlight and Finder.

* If you are using Snow Leopard (10.6) you will need to use this line instead: setenv
DYLD_FRAMEWORK_PATH /Applications/WebKit.app/Contents/Frameworks/10.

Reported by nmutnick on 2009-11-23 14:35:45

[dankurka]

thanks for your response, I can't achieve it like this. Under snow leopard, I've
solved the problem by doing a .bashrc file in my home and add this command into:

export DYLD_FRAMEWORK_PATH=/Applications/WebKit.app/Contents/Frameworks/10.6

mode working again

2. tried creating and editing ~/.bashrc with
export DYLD_FRAMEWORK_PATH=/Applications/WebKit.app/Contents/Frameworks/10.6
that did't work
3. tried same in /etc/.profile -didn't work
4. tried same in /etc.launchd.conf - didn't work!

Some kind soul please help.

I use mac snow leopard and eclipse (Version: 3.4.1
Build id: M20080911-1700) and was able to get the solution to work. What version of
gwt are you using?  There was recently another problem with the BootStrapPlatform
class when I upgraded to Snow Leopard.  I think it was due to Apple changing the
default jdk.  

I right clicked on my project (gwttest17 in this example), and selected properies.
 I
attached the screen that pops up as attachment gwt_safari_fix1.tiff.  Next I select
"Run/Debug Settings" from this screen, and get the attachment gwt_safari_fix2.tiff.

I then added the property that you see.

Here is the link that tells you how to get gwt to work with snow leopard operating
system upgrade on the mac.  Hosted mode only works with the 32 bit jdk, and snow
leopard defaults to 64 bit jdk 1.6.  I tried this fix and it worked for me.  I don't
know if this is your problem, but am throwing it out there just in case the safari
upgrade isn't your problem.

did you look at my other posting.  You might have 2 different problems going on here.
