[jdom-interest] JDOM cause JVM crash?

I don't have any threads in my java code, it happens to any xml documents that the web app tried to read. Since the web app runs in a servlet engine (tomcat) which has its threads to handle the request, it could be somthing there. I have the same programs runs on Window 98/2000 and Linux (RH 7.2) with no problem at all. Only when we move the programs to a Solaris box that the JVM crash happen, and the stack trace always the same (throw at SAXBuilder).

  I had a similar error message Unexpected Signal : 10 occurred at.....

  when I accidentally had multiple java threads calling a single native thread. No idea if this applicable to your situation!!!

  I am using JDOM in Solaris / JDK_1.3.1_04 / Tomcat 4.0.4, and JVM crashes whenever I try to read a xml using JDOM. Can anyone possible shed some light on this?
