           Summary: Iced tea openjdk1.6 and jdk1.7 crashes in remote x
                    server (cygwin) environment
           Product: IcedTea
           Version: unspecified
          Platform: PC
        OS/Version: Linux
            Status: NEW
          Severity: normal
          Priority: P2
         Component: IcedTea
        AssignedTo: unassigned at icedtea.classpath.org
        ReportedBy: balajiraman at ge.com


A simple java application crashes in remote x server environment for both
openjdk1.6 and jdk1.7 when xrendering pipeline is enabled. Both the jvm and the
xserver crashes. The remote x server uses NX (www.nomachine.com) technology for
compression of X traffic. 

Some interesting findings:
The xrendering pipeline does not crash in remote x server environment if we
change the look feel to one of our custom look and feel.

The xrendering pipeline does not crash for any look and feel in LOCAL X SERVER
environment on Cent 0S 5.3.

There are no crash logs, but while running the JGears demo using a debugger we
found that a crash occured during a call to sun.java2d.SunGraphics2D.

I am not quite sure whether it is a java issue, or x server issue or NX issue.
