Error when running ant hosted on OS X 10.6

[Kyle Hayes]

I created a new project from webAppCreator in OS X 10.6. It created
without any problems, however when I try to run the command "ant
hosted", I receive the following output:

-------------

Any ideas on how to fix this? Thanks!

I have the same.
I created ticket http://code.google.com/p/google-web-toolkit/issues/detail?id=4220
for it.

[Jim Douglas]

Same crash here trying to start hosted mode inside Eclipse using Mac
OS X Leopard after installing that Safari update. I added the first
part of my crash report to http://code.google.com/p/google-web-toolkit/issues/detail?id=4220.

I have solution for it. UGLY UGLY UGLY solution, but it allows me to
work until problem is not fixed:

Heh, you're right this is really ugly. However, it may be worth a try,
but not on my work code ;-)

I use it only on development enviroment.
To production I use original GWT.

Someone else thinks similar to me

I installed your new jar and I'm still getting the following error:

Here is my install location contents:

$ ls /usr/local/gwt-mac-1.7.1/

==============

The gwt-dev-mac.jar.bak is the old jar and the non.bak is the
*patched* one. Yet the error is still complaining about not finding
libgwt-ll.dylib.

This is not my jar. ;)

I checked out releases/1.7 from GWT svn and I compiled it myself. Then
I use whole generated GWT distro, not only new JAR.


If You don't want build GWT yourself I can send You my.

[Hayes, Kyle]

Yes that would be great!

Can be that (10.6.1, safari 4) uses 64bit architecture instead 32?
Have a look to: http://kb2.adobe.com/cps/509/cpsid_50983.html

[Chris Ramsdale]

Thanks for all of your input regarding this issue. We were able to
reproduce the problem and have found that it is a result of an issue
within the 4.0.4 version of JavaScriptCore. We have reported the issue
to the WebKit team (http://trac.webkit.org/changeset/50964) and an
update was made but it will take some time to work it's way into
another Safari update. In the meantime to continue using GWT 1.7.1,
and prior, the safest workaround would be to revert back to Safari
4.0.3. The patches that have be suggested within this thread will work
but may result in other inconsistencies as objects are not properly
being released.

I have also tested out the latest MS2 release of GWT using 4.0.4 and
had no issues running in hosted mode (now referred to as Development
Mode). GWT MS2 is available here:
http://code.google.com/p/google-web-toolkit/downloads/list?can=1&q=2.0+Milestone+2

I will keep everyone posted with any further updates.

I've reverted to Safari 4.0.3 using a Time Machine backup (just
replacing Safari.app) and it has not fixed the problem. Based on this
Apple support thread — http://discussions.apple.com/thread.jspa?threadID=2032790&tstart=0
— it seems to truly revert you'd need to restore your entire system to
before 4.0.4 was installed (if you have Time Machine set up).

I can't say if that will work for sure because I don't want to revert
my entire system, but I figured someone might want to know :).

My experience was much worse when reverting to 4.0.3. My Mac would no
longer boot up and got stuck on the Apple loading screen. I zapped the
PRAM, attempted to boot in safe mode, repaired disk permission, even
re-installed OS X. I'm now at the point of just reformatted my drive
and am installing OS X fresh. Luckily I was able to boot into Target
Disk Mode last night to back up the drive.
