Behrooz Nobakht commented on LOG4J2-909:
----------------------------------------

Confirm that 

{code:java}
System.setProperty("log4j2.disable.jmx", Boolean.TRUE.toString());
{code}

resolves the situation although the stack trace was not blocking.

This ticket anyway may be useful regarding JDK changes.
