The following 2 tests are planned for this feature:
1. Execute "jps" and "jcmd -l" with several JVMs running inside the containers.
    Ensure jps/jcmd that runs on a host system can see the Java processes running inside containers, and report correct PIDs.
    This only works if access is configured correctly.

2. Exercise PerfDataFile.getFile(..)

Fix request [17u] I backport this for parity with 17.0.7-oracle. No risk, only a test change. Clean backport. Test passes. SAP nighlty testing passed.

Here is the preliminary updated change: http://cr.openjdk.java.net/~mseledtsov/8195809.pre.01/ It works, but needs some cleanup and more testing. It can be used to reproduce a problem with 'jcmd help'. (jcmd -l works).
