Hi all, In Hibernate trunk, the following tests are failing: In JBC 2LC provider: MVCCIsolatedClassLoaderTest.testClassLoaderHandlingNamedQueryRegion MVCCIsolatedClassLoaderTest.testClassLoaderHandlingStandardQueryCache In Infinispan 2LC provider: IsolatedClassLoaderTest.testClassLoaderHandlingNamedQueryRegion IsolatedClassLoaderTest.testClassLoaderHandlingStandardQueryCache They're failing because AccountHolder is being loaded with the system classloader rather than the SelectedClassnameClassLoader. The reason for this is that as a result of http://opensource.atlassian.com/projects/hibernate/browse/HHH-2990, SerializationHelper.CustomObjectInputStream now takes the classloader in the constructor. And during the test, SerializableType.fromBytes passes null as classloader to this constructor. The null comes from getReturnedClass().getClassLoader() below, which has been added as a result of 2990. private Object fromBytes(byte[] bytes) throws SerializationException { return SerializationHelper.deserialize( bytes, getReturnedClass().getClassLoader() ); } Now, shouldn't we use Thread.currentThread().getContextClassLoader() instead of getReturnedClass().getClassLoader()? Previously, that's what would have happened. I dunno why getReturnedClass().getClassLoader() was added though. I've just tested using Thread.currentThread().getContextClassLoader() change and the tests pass now. Steve?
