Examples with ObjectMonitorReferencePointer com.ibm.j9ddr.vm29.pointer.ObjectMonitorReferencePointer used on opensource projects

Example 1 with ObjectMonitorReferencePointer

use of com.ibm.j9ddr.vm29.pointer.ObjectMonitorReferencePointer in project openj9 by eclipse.

the class RootScanner method scanMonitorLookupCaches.

protected void scanMonitorLookupCaches() throws CorruptDataException {
    setReachability(Reachability.WEAK);
    GCVMThreadListIterator vmThreadListIterator = GCVMThreadListIterator.from();
    while (vmThreadListIterator.hasNext()) {
        J9VMThreadPointer walkThread = vmThreadListIterator.next();
        if (J9BuildFlags.thr_lockNursery) {
            ObjectMonitorReferencePointer objectMonitorLookupCache = walkThread.objectMonitorLookupCacheEA();
            for (long cacheIndex = 0; cacheIndex < J9VMThread.J9VMTHREAD_OBJECT_MONITOR_CACHE_SIZE; cacheIndex++) {
                ObjectMonitorReferencePointer slotAddress = objectMonitorLookupCache.add(cacheIndex);
                doMonitorLookupCacheSlot(slotAddress.at(0), slotAddress);
            }
        } else {
            /* Can't implement this because walkThread.cachedMonitor field does not exist as we've never had a vm29 spec yet with the condition: 
				 * (!J9BuildFlags.thr_lockNursery && !J9BuildFlags.opt_realTimeLockingSupport)
				 * 
				 * // This cast is ugly but is technically what the c-code is doing 
				 * ObjectMonitorReferencePointer cachedMonitorSlot = ObjectMonitorReferencePointer.cast(walkThread.cachedMonitorEA());
				 * doMonitorLookupCacheSlot(walkThread.cachedMonitor(), cachedMonitorSlot);
				 */
            throw new UnsupportedOperationException("Not implemented");
        }
    }
}

Example 2 with ObjectMonitorReferencePointer

use of com.ibm.j9ddr.vm29.pointer.ObjectMonitorReferencePointer in project openj9 by eclipse.

the class SimpleRootScanner method doMonitorLookupCacheSlot.

@Override

    try {
        J9ThreadAbstractMonitorPointer monitor = J9ThreadAbstractMonitorPointer.cast(slot.monitor());
        doSlot(J9ObjectPointer.cast(monitor.userData()), VoidPointer.cast(monitor.userDataEA()));
    } catch (CorruptDataException e) {
        EventManager.raiseCorruptDataEvent("Errror accessing object slot from J9ObjectMonitorPointer: " + slot.getHexAddress(), e, false);
    }
