Hi Andreas,
What's the gtk version that ships with the new OpenSolaris build? SWT has
had various problems with GTK 2.18, and one that looks like it could be
related to what you're seeing is
https://bugs.eclipse.org/bugs/show_bug.cgi?id=291257 . Can you see if
setting Solaris environment variable GDK_NATIVE_WINDOWS=true before running
eclipse helps? If not then please log a report with all of your information
with swt at
https://bugs.eclipse.org/bugs/enter_bug.cgi?product=Platform &component=SWT .
Thanks,
Grant

Subject: OpenSolaris: Eclipse/SWT hangs in GTK OS call when trying to change
fonts
Date: January 8, 2010 8:33 AM
Hi Eclipse community,
on my brand new OpenSolaris build 129 x64 installation, Eclipse IDE hangs
when trying to change fonts (Window - Preferences - General - Appearance -
Colors and Fonts, then clicking the "Edit" button to change e.g. the CVS
console font) or colors. I think this hang happens when trying to open a
standard GTK font or color chooser.
Most surprisingly (although I would expect the exact same event handlers
being configured for both actions), when double-clicking on the currently
configured font name/color instead of using the "Edit" button, there is no
hang and the GTK font and/or color chooser opens up just fine...!?
I have tried with the plain Eclipse 3.5.1 package from eclipse.org/downloads
as well as with the 3.4.2 build available from the opensolaris.org/dev
repository, and also with both the most recent 1.6.0_17 and 1.5.0_22 JDKs
and the client as well as the server JVM.
While the main thread is hung, I am getting the following jstack and pstack
traces (full thread stacks: see attachments):

As the hang does only happen when using the "Edit" button, but not when
double-clicking on the configured font/color, am I correct in assumin that I
am more likely hitting a bug in the Eclipse SWT rather than in OpenSolaris
GTK infrastructure!?
Interestingly, I have also tried with Eclipse 3.5.1 on the official Open
Solaris 2009.06 osol_111b build (running from the live DVD), and opening the
font dialog works fine here even through the "Edit" buttons with JVM
1.6.0_13.
Please find the stack traces on OpenSolaris builds 129 and 111b attached.
It's most interesting that while on build 111b, the whole font dialog
processing (using the exact same Eclipse 3.5.1 binaries) runs from within
one single thread (thread#1/lwp#1), the same thing in 129 uses two threads:
thread#1/lwp#1 uses ContinueInNewThread to spawn thread#2/lwp#2.
Maybe this dynamic thread creation is unexpected behavior from the SWT
perspective and causes the hang!?
Many thanks for looking into this & best regards,
Andreas
