SWT in Swing breaks in SWT 3.7 on OS X [message #688453]

Hey all.
I just filed bug 350312 to report this issue but wanted to also raise it
here in case anyone has any ideas for a workaround. I really need this code
to work sooner rather than later. I upgrade to 3.7 to fix an issue with web
browsers in Linux.

A brief summary:
I run an RCP application that uses Swing internally for a number of its
editors. The Swing-based editor now requires an embedded web browser for an
advanced feature. I can achieve this fairly simply in Eclipse/SWT 3.6 but
in 3.7 I get stack overflows if I have one embedded SWT component or a VM
crash if I have several. This all works fine in 3.7 on Windows and Linux.
It also works fine in 3.6 on all 3 platforms.

Stacktrace:
Exception in thread "main" java.lang.StackOverflowError

java version "1.6.0_24"
Java(TM) SE Runtime Environment (build 1.6.0_24-b07-334-10M3326)
Java HotSpot(TM) 64-Bit Server VM (build 19.1-b02-334, mixed mode)

org.eclipse.swt.cocoa.macosx.x86_64.source_3.7.0.v3735b.jar

I have a fairly short snippet to reproduce the issue attached to the bug.

Please help.

Thanks.

So... No help then? Does anyone know who is responsible for the Cocoa
implementation of SWT? I tried to look at what changed between 3.6.2 and
3.7 but the answer for Shell.java was pretty much everything.
