RFR of JDK-8171142: jdk_rmi registry test fail to clean up on failure

[Roger Riggs]

Hi Hamlin,

test/javax/rmi/PortableRemoteObject/ConcurrentHashMapTest.java:

   line 130: trivial, but please add a space in "!=null"...

Note: on Windows there is no difference between Process.destroy vs 
Process.destroyForcibly,
but on Linux it it is the difference between kill -15 and kill -9.

Using destroyForcibly would be more certain as to the death of the 
subprocess.

Otherwise looks fine

Thanks, Roger
