TreeCacheListener in PojoCache gets nodeModify events for invalid objects
--------------------------------------------------------------------------
Key: JBCACHE-760
URL: http://jira.jboss.com/jira/browse/JBCACHE-760
Project: JBoss Cache
Issue Type: Bug
Security Level: Public (Everyone can see)
Components: PojoCache
Affects Versions: 1.4.0.SP1
Reporter: Nitzan Niv
Assigned To: Manik Surtani
In PojoCache with a registered event listener, when inserting a collection (Map, List) to
the cache, the listener gets events for the creation and then the modification of the
collection object. On a nodeModify() event (with pre==false), if you call the cache's
getObject with the received fqn you get the following runtime exception (which did not
occur on 1.3.0SP2 in a similar scenario).
I believe the modification event is raised before the collection is "really"
inserted into the cache, so the fqn points to an invalid object.
java.lang.RuntimeException: TreeCacheAopDelegate._getObject(): null AOPInstance.

Ben Wang commented on JBCACHE-760:
----------------------------------
Can you verify that this is also a problem with regular pojo? I'd think getObject in
nodeModify will run into the same problem.
On a separate node, I am switching to pojo-based event listening. So this will not be a
problem anymore in 2.0 release.

Attached is a modified CollectionClassHandler that resolves this issue and a modified
TestCase that checks it.
The problem is in collectionObjectPut() and it is resolved by putting an initialized
AOPInstance in the FQN before putting the collection's Class there.

getObject with the received fqn you get the following runtime exception (which did not
occur on 1.3.0SP2 in a similar scenario).
I believe the modification event is raised before the collection is "really"
inserted into the cache, so the fqn points to an invalid object.

To recreate the problem I use a test case similar to TreeCacheListenerTest but with a
PojoCache. The test is:
public void testNodeCreatedAndModifiedMapEvent() throws Exception {
EventLog el = new EventLog(cache);
cache.addTreeCacheListener(el);
Map data = new HashMap();
data.put("key", "value");
cache.putObject("/hello/world", data);
...
}
and the relevant listener code:
public void nodeModify(Fqn fqn, boolean pre, boolean isLocal) {
events.add("modify "+
(pre? "about to modify " : "Modified ") +
(isLocal? "local " : "remote ") + fqn);
if(this.cache != null && !pre) {
try {
cache.getObject(fqn);
}
catch (Exception e) {
events.add(e);
e.printStackTrace(System.err);
}
}
}

TreeCacheListener in PojoCache gets nodeModify events for invalid
objects

Key: JBCACHE-760

Project: JBoss Cache
Issue Type: Bug
Security Level: Public(Everyone can see)
Components: PojoCache

Fix For: 2.0.0, 1.4.0.SP2

In PojoCache with a registered event listener, when inserting a collection (Map, List) to
the cache, the listener gets events for the creation and then the modification of the
collection object. On a nodeModify() event (with pre==false), if you call the cache's
getObject with the received fqn you get the following runtime exception (which did not
occur on 1.3.0SP2 in a similar scenario).
I believe the modification event is raised before the collection is "really"
inserted into the cache, so the fqn points to an invalid object.

[ http://jira.jboss.com/jira/browse/JBCACHE-760?page=all ]
Ben Wang resolved JBCACHE-760.
------------------------------
Resolution: Done
1. Checked in both the test case and fix to 1.4.0SP2
2. Also fix it in 2.0. However, the notification event is different is 2.0 now.
