Symptoms

The admin server on WebLogic Server (WLS) 12.2.1.2 fails to start when a custom auditor (built by following the SimpleSampleAuditor documentation at http://docs.oracle.com/middleware/12212/wls/DEVSP/aud.htm#DEVSP425) is enabled and Java Hot Swap (which is enabled by the enableHotswap switch at the command line which adds "-javaagent:/refresh/oracle/middleware/fmw12212/wlserver/server/lib/diagnostics-agent.jar" to the startup command) is also enabled.

The following error is observed:
