The fix works for me.

I also found this bug with my own application using a GMF-based editor.

eclipse.buildId=I20090528-2000
java.version=1.6.0_07
java.vendor=Apple Inc.
BootLoader constants: OS=macosx, ARCH=x86_64, WS=cocoa, NL=en

We're seeing this same issue under OS X with:

eclipse.buildId=I20090611-1540
macosx
-ws
cocoa
-arch
x86
macosx
java.vendor=Apple Inc.
java.version=1.5.0_16

The problem was not present in Eclipse 3.4.2 but in 3.5 it causes some features to fail.

I can reliably reproduce this problem as well. Bug fix works for me too.

Can someone please make the necessary commits to get this into the 3.6 stream, as well as the 3.5SR2, if there will be one?

Thanks.
