Hi James, 

If you set it before JAVA_OPTS then, how Java Command will pick it up this value at all? 

In fact I tried several places to modify the order and try to see, if its gets started, but it is not and always throwing an error. 

The first place in the standalone.conf.bat, first setting of JAVA_OPTS happens at line no 49. 

Here is the full console log for the reference.  In case specific things are working, I must be able to see the jmx metric on the specified port.  [http://localhost:9080/metrics]

 

In case, if you have working, instance, please share me the standalone.conf.bat and standalone.bat file for comparison purpose.
