PersistentMap.put(), remove() may return UNKNOWN object that can cause ClassCastException
in client code
--------------------------------------------------------------------------------------------------------
Key: HHH-2142
URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-2142
Project: Hibernate3
Type: Bug
Components: core
Versions: 3.2.0.cr5
Reporter: Andrzej Miazga
Here is some code in Hibernate 3.2.0cr5 that may cause this behaviour. I'm not sure if
this is a bug but it surely affects the client code.
AbstractPersistentCollection:
protected Object readElementByIndex(Object index) {
if (!initialized) {
...
return persister.getElementByIndex( entry.getLoadedKey(), index, session, owner );
}
...
return UNKNOWN;
}
PersistentMap (extends AbstractPersistentCollection):
public Object put(Object key, Object value) {
if ( isPutQueueEnabled() ) {
Object old = readElementByIndex( key );
queueOperation( new Put( key, value, old ) );
return old;
}
...
So, there is a possibility to return UNKNOWN instance (MarkerObject) to the client code as
the result of Map.put().
In version 3.1.3 this worked fine, but the implementation was different:
public Object put(Object key, Object value) {
Object old = isPutQueueEnabled() ?
readElementByIndex(key) : UNKNOWN;
if ( old==UNKNOWN ) {
write();
return map.put(key, value);
}
...
}

-------------------------------------
This is definitely happening. I'm getting ClassCastException to MarkerObject from
this line:
EnabledFilter filt = list.getEnabledFilters().remove(className);
Doing the get() and remove() as separate steps works fine. This is with JBoss 4.0.5.GA.

------------------------------------
I'm also getting a MarkerObject in version 3.2.0 as a result of a put and a remove. I
confirmed via debugger that it is coming from
AbstractPersistentCollection.readElementByIndex(Object index).

-------------------------------------
The ClassCastException issue when using remove() is still present in 3.2.3.ga, however the
put() issue was resolved in HH-2476.

Please note that the patch for HHH-2584 also solves the problem that the value isn't
removed if the Map is not yet initialized.
