Juozas Baliuka commented on HHH-1293:
-------------------------------------

Thread implementations are different (JVM on some linux kernels uses child process and shared memory to implement multithreading, it can depend on JVM settings and implementation) and can produce many anomalies if code is not thread safe. The right way is to make application code thread safe, workarounds can help to hide a problem, but not to solve it.

> The exception varies with the actual persistent class in use. Most people seem to be using JDK 1.5 and Linux. Some reports say that the exception does not happen from the very start of the application, but it takes "several invocations"/"some time" until it appear, but then it appears very often.
