Description

We started seeing Python DTest failures that point to Jolokia agent. 

In  one of the latest J11 runs I noticed: 

stdout = b"WARNING: An illegal reflective access operation has occurred\nWARNING: Illegal reflective access by org.jolokia.jvma...rt '8778' is already occupied.\nPlease check the standard output of the target process for a detailed error message.\n" stderr = None, retcode = 1

I checked Jolokia  official page and it seems they added the Java 11 support with 1.7 and we are on 1.6 yet.

So I suspect this might be our solution. To be investigated.
