Webrev:
http://cr.openjdk.java.net/~sspitsyn/webrevs/2017/hotspot/8176831-jmm-dead.1/


Summary:

   It was found at the review of the 8155672 that the function
   jmm_GetLoadedClasses() defined in services/management.cpp
   is not really used in the jmm_interface. This function and
   dead code associated with its implementation is removed.

Testing:
   The nsk.monitoring and jtreg jdk_management tests are in progress.


Thanks,
Serguei
