Hi,

the test org.infinispan.jmx.RpcManagerMBeanTest.testEnableJmxStats  always fails on all environments for ER10 build.

This bug is completely the same as the ISPN-2756 (in JIRA), but I run the tests for infinispan latest version and it works without failures, so issue refers only to JDG 6.1.0.ER10 build.

The log is:
