The exception is thrown because the class was loaded by a previous version of the application classloader. CacheableCommandImp.execute should detect and handle a ClassCastException.Problem conclusion Dynacache will now catch and handle a ClassCastException in the CacheableCommandImpl.execute() method and serialized/deserialized the command output to correct the classloader change.Temporary fix WAS_Dynacache_03-14-2003_5.0.0_cumulative_TestComments
