Hi Chris, Would jdk.internal.vm be appropriate for this VMSupoprt class?
VMSupport::getAgentProperties simply calls JVM_InitAgentProperties. java.management could call JVM_InitAgentProperties directly. src/jdk.jdwp.agent/share/native/libjdwp/util.c JDWP calls it and needs to be updated. VMSupport.getVMTemporaryDirectory() is for jdk.jvmstat to use and I suggest to move this method to jdk.internal.perf.Perf.
