I think you have a JVM installation issue. You indicate that you are running JDK 1.6, but the error identifies the JVM as: Java VM: Java HotSpot(TM) Server VM (1.5.0_01-b08 mixed mode) and later it says: vm_info: Java HotSpot(TM) Server VM (1.5.0_01-b08) for windows-x86, built on Dec 6 2004 19:33:54 by "java_re" with MS VC++ 6.0 but among the DLLs listed are: 0x7c340000 - 0x7c396000 C:\Program Files\Java\jre1.6.0\bin\msvcr71.dll 0x6d840000 - 0x6dba5000 C:\Program Files\Java\jre1.6.0\bin\server\jvm.dll Actually, that last line concerning the jvm.dll leads me to believe that someone copied over a 1.5 JVM DLL into the 1.6 JVM directory.
