Please find below a thread dump from a "hanged" process. Also, I watched the database and didn't find any locks there. There are a variable amount of databases processes belonging to the test case, but none of them are "locking" any table / record (ie: no records in "v$lock" table in oracle displays "1" in the "block" column). As per the Thread Dump, it seems it is stuck in some infinite loop (Thread.sleep inside a while, on ReaderPerfTestCase).
