RFR: JDK-8147447: [TESTBUG] serviceability/tmtools/jstack/WaitNotifyThreadTest.java test fails

[Staffan Larsen]

isCompMode() will fail if the VM is started with both -Xcomp and -Xmixed.

We need to find a better way to check if compiled mode is being used. Perhaps System.getProperty("java.vm.info").contains("compiled”) ?
