strange exception during JUnit tests with EJB3 embeddable

[ramazanyich]

We use EJB3 embeddabel RC8 for JUNIT tests of our EJBs.
After moving to RC8 version we have strange problem on JDK1.5_07 running on windows.
From junit log file:

Strange thing if we run the same test on Solaris JVM (AMD64 platform) with JDK1.5_01 we never had such error.
Does someone had such error ?

[ramazanyich]

After some investigations I found that some times tests can be run without any changes in environment.
But I didn't found why and when it happens.
After one successful run it take some time until tests can be run again successfully. It seems like somewhere some kind of caching is done on system memory or on file system level and after some timeout it is freed.
How to find and disable such caching ?
