RFR(S) : 8219139 : move hotspot tests from test/jdk/vm

[Igor Ignatyev]

Hi Alan,

I double checked, the test is linked w/ -ljli, and calls JNI_CreateJavaVM from libjli.so. hence I'll leave JniInvocationTest in jdk/tools/launcher.

I suspect it may be directly (or indirectly) reading the CFBundleExecutable property from Info.plist and calling the JNI_CreateJavaVM function in libjli (not libjvm). We probably need more tests in this area and also a bit more archaeology to see whether this was a supported interface in Apple's JDK.
