When this happens, the exception is not caught, and the call never gets a response - the client just hangs. Additionally, the OOME propagated all the way to the top of the IPC handler and caused the handler. Plus, the Handler upon exit only logged to stdout and not to the log4j logs. -- This message is automatically generated by JIRA.
