With jolokia 1.3.5 loaded into Apache Cassandra jvm as an agent I hit once:

ERROR [Jolokia Agent Cleanup Thread] 2017-04-15 12:47:51,639  CassandraDaemon.java:207 - Exception in thread Thread[Jolokia Agent Cleanup Thread,5,main]
java.lang.NullPointerException: null
	at org.jolokia.jvmagent.CleanupThread.joinThreads(CleanupThread.java:101) ~[jolokia-jvm-agent.jar:na]
	at org.jolokia.jvmagent.CleanupThread.run(CleanupThread.java:60) ~[jolokia-jvm-agent.jar:na]

This is not repeatable, happened only once so far.
