RFR 8142398: IllegalAccessException Class sun.usagetracker.UsageTrackerClient$4 (module java.base) can not access a member of class java.lang.management.ManagementFactory (module java.management)

[Jaroslav Bachorik]

Please, review the following change

Issue : https://bugs.openjdk.java.net/browse/JDK-8138677
Webrev: http://cr.openjdk.java.net/~jbachorik/8138677/webrev.00

The problem is that the class UsageTrackerClient is accessing 
RuntimeMXBean.getInputArguments() method via reflection to avoid static 
dependency. However, with functional module boundaries this fails.

Since the functionality provided by RuntimeMXBean.getInputArguments() is 
not, in fact, specific to the management subsystem, it makes sense to 
move it out of jmm.h to jvm.h

Full suite of SVC tests was run against this change successfully on all 
platforms.


Thanks,
