Hi, is there any way to get a clustered condition when using express mode?

The following code

Code:

 ReadWriteLock lock = toolkit.getReadWriteLock("TheRWLock");
 
 Lock wl = lock.writeLock();
 
 Condition cond = wl.newCondition();

Seems to produce a cluster aware condition (org.terracotta.locking.TerracottaCondition), however there's no way to share it across distinct VMs.

Which version of terracotta you are using , in the current version by default it's shared across VM's.

Rajoshi I tested in both 3.7.2 and 3.7.4. The test is very simple: Just call await in one or more nodes, and launch another an call signalAll(). The previous nodes remain blocked.

The examples I found work only with DSO:

Code:

  protected Condition getCondition(final Lock lock, String name) {
     Assert.assertTrue(Terracotta.isManaged(lock));
     return Terracotta.lookupOrCreateRoot(name, new Callable<Condition>() {
       public Condition call() throws Exception {
         return lock.newCondition();
       }});
   }

I think that, if possible, the returned lock from writeLock() should be a Terracotta specialization with a getCondition(String name). Even in the same node newCondition() will return distinct conditions (as is expected).
