AffineEdges-crash on Linux-systems

Hi,
the VM crashes (on two different systems) while rendering a PieChart :
System 1:
java . . . . : build 1.4.1_02-b06
tomcat . . . : tomcat 4.0.6
apache . . . : apache1.3
OS . . . . . : Linux 2.4.20-64GB-SMP

System 2:
JDC
java . . . . : build 1.4.1_02-b06
tomcat . . . : tomcat 4.0.6
apache . . . : apache1.3
OS . . . . . : Linux version 2.4.24(Red Hat Linux 7.3 2.96)

The error message is:

"An unexpected exception has been detected in native code outside the VM.
Unexpected Signal : 11 occurred at PC=0x98A3AAFF
Function=mlib_AffineEdges+0x77F
Library=/vocal/local/j2sdk1.4.1_02/jre/lib/i386/libmlib_image.so

Cannot obtain thread information"

The problem seems to be related to the antialiasing - setting of my PieChart and does not occur on Windows-systems.

I would appreciate any help...

Simon

Anything that crashes the JVM will be something that Sun will want to know about. Last year there was a similar type of problem that we reduced to a simple test case - I reported it via Sun's bug database and it got fixed reasonably quickly. See this thread for details:

My own motivation to chase bugs for Sun has diminished following an incident at the end of last year when one of their forum administrators told me that announcing new releases of JFreeChart in the java.sun.com forums is "considered a form of spam". But if you find the underlying cause of the problem, I'll try to add a workaround (if it is possible) to JFreeChart to cover until the bug in the JDK is fixed.
