Hotspot VM Error

[Andy Parsons]

We recently began testing our Java server application on HP-UX. While it is stable on other VM's, we consistently crash the VM on HP with the following result logged:

#
# HotSpot Virtual Machine Error : 11
# Please report this error to HP customer support.
#
# Java VM: Java HotSpot(TM) VM (1.3.1 1.3.1.02-JPSE_1.3.1.02_20011206 PA2.0 mixed mode)
#

It appears to be a VM bug. Is there anything we can pursue as a workaround besides revertin to "classic" mode?

Detailed log below:

Hi Andy,

Check this sites for all Java patches and compare it with your system. If you are missing anything download and install it:

HTH,

Andy,

As Shiju has said, check your patches. if you don't have dec 2001 patch bundle installed, then you need too. Personally, I use the custom patch manager to "find" patches for me.

Hopefully this problem is resolvable with patches, as advised by the other replies. If there is any native code called by the Java application, you may wish to inspect what's going on there. You might find the debugger (either gdb or dde) to come in handy. Since signal 11 is often a bad pointer access, you can try looking for that if there is native code called by this application and the patches don't make any difference.

If you're still experiencing the problem after all that, then maybe you've really found a bug in the JVM that should be reported to HP.
