This is an internal JVM error. It doesn't appear to be an OutOfMemoryException. I would suggest talking to Sun about this one. You may also want to upgrade to a newer JVM.

Hi all,
I am not sure this is the right context for my question..If it's not, feel free to ignore it.
I received a 'strange' error message from java VM while I was executing an application which involved 500 threads running httpclient in multithread mode on a standard pc. Each thread was executing several http requests in sequence.
I am not very fond of java, anyway it seems to me that the problem could have been generated by an OutOfMemoryException thrown by httpclient. I can't show you a log but the exception was actually thrown at run-time. If there are any clues suggesting that the problem could lie in the httpclient instead of being a consequence of a memory shortage, please let me know.
Here is the message i got:
An unexpected exception has been detected in native code outside the VM.
