[REDO] Add a compilation timeout flag to catch long running compilations

XMLWordPrintable

    • b13

      We should add a compilation timeout flag to the VM to catch long running compilations. We could piggy-back on -XX:+CITime

      --- a/src/hotspot/share/runtime/timerTrace.cpp
      +++ b/src/hotspot/share/runtime/timerTrace.cpp
      @@ -75,6 +75,9 @@ TraceTime::~TraceTime() {
         if (_accum != NULL) {
           _accum->add(_t);
         }
      + if (_t.seconds() > 3) {
      + assert(false, "Compilation timeout in phase %s", _title);
      + }
         if (!_verbose) {
           return;
         }

      As part of this, or with a separate change, we might also want to improve CITime/CITimeVerbose/CITimeEach to narrow down the cause of the timout.

      The disadvantage of above solution is that it would not catch endless looping compilations. For that, we would need a watcher thread (or maybe we can use an existing VM thread for that?).
