[hibernate-dev] All the tests in hibernate-ogm pass with Voldemort but PerfTest didn't even run

Hi, I'm not sure if there is already an implementation for Voldemort and also not sure if anyone even wants to use Voldemort with hibernate ogm but that's where I started experimenting hibernate ogm and now my implementation passes all the supplied test cases except one test class called PerfTest. It's located in the package named "org.hibernate.ogm.test.perf". Every time I try to run it changing VM arguments, I get OutOfMemory exception and also an exception saying "ARJUNA: some error message". As the result, the commit fails. Has anyone succeeded to run the test cases in the class ? If so, what would you set the VM options ? Thank you Seiya
