      JavaTest Message: Test threw exception: java.lang.RuntimeException: Test ERROR java.lang.RuntimeException: 'compiler detected' missing from stdout/stderr

      JavaTest Message: shutting down test

      STATUS:Failed.`main' threw exception: java.lang.RuntimeException: Test ERROR java.lang.RuntimeException: 'compiler detected' missing from stdout/stderr


      The test reports that it cannot find the 'compiler detected' pattern, but the
      root cause is probably this:

      Error attaching to process: Can't create thread_db agent!
      sun.jvm.hotspot.debugger.DebuggerException: Can't create thread_db agent!
