Description Rhett Savage CLA 2003-06-16 15:32:49 EDT 
A simple plug-in which merely puts up a Swing dialog or creates a JFrame and
makes it visible immediately crashes Eclipse 2.1 using RedHat 8.0 and JDK 1.4.1.
- the same experiment succeeds in showing the Swing windows under Windows and,
apparently, Gentoo Linux. 

Parts of the error and stack-trace are pasted below:

An unexpected exception has been detected in native code outside the VM.
Unexpected Signal : 11 occurred at PC=0x4D75E917
Function=_XtSortPerDisplayList+0x57
Library=/usr/X11R6/lib/libXt.so.6

Moving to SWT...
Comment 2 Steve Northover CLA 2006-04-05 12:20:58 EDT 
The code base has changed significantly since this bug was reported.  If it is still happening for you, please reopen this bug report.  For example, we there are no MPeers in the JDK 1.5 X embedded frame.
