Frederic,

GCNotificationRequest *request = getRequest();

request variable also leaks memory because it will never be deleted on
CHECK return path. Could you fix it too?

Further:

 211     JavaCalls::call_virtual(&result,
 212                             gc_mbean_klass,
 213                             vmSymbols::createGCNotification_name(),
214 vmSymbols::createGCNotification_signature(),
 215                             &args,
 216                             CHECK);
 217     if (HAS_PENDING_EXCEPTION) {
 218       CLEAR_PENDING_EXCEPTION;
 219     }
 220
 221     delete request;

The CHECK at @216 will cause a return if there is an exception pending so 217-219 is dead code. This also indicates some confusion about what exceptions this method can leave pending. Or it may be that the CHECK at #216 was meant to be just THREAD. ??

(Strange this is the second example I've seen of this today!)

Here's a small fix (one line) for CR 7143760  Memory leak in
GarbageCollectionNotifications

There's a missing HandleMark at the beginning of the
GCNotifier::sendNotificatin() method. Without this HandleMark, all
handles used when creating GC notifications are kept alive causing a
double leak: in the Java heap and in the thread local handle area of the
service thread.

Here's the CR:
http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=7143760
(Warning, the changeset referenced in the CR is not the
one containing the original bug).

Here's the webrev:

Thanks,
