Summary: BMP beans: ejbStore not called post find
Initial Comment:
If a BMP bean executes a finder method, the container
will first call ejbStores to synch beans with the
datastore as necessary (per the EJB spec). However, if
this happens, an ejbStore will not then be called at the
end of transaction (in violation of the spec).
The simple test case attached is a bmp bean called by
a client. The ejbStore method just writes out the data to
System.out, so no configuration of data sources is
necessary to run this. The final value of the variable (10)
is never written to System.out.
Note that this bug was introduced in the 3.x series. It is
not present as of JBoss 2.4.4.
A first glance at the source code from the nightly
snapshot suggests that GlobalTxEntityMap might be
the culprit, where:
public void syncEntities(Transaction tx)
throws TransactionRolledbackException
{
Collection entities = null;
synchronized (m_map)
{
entities = (Collection)m_map.remove(tx);
}
removes the entities from the map whenever a synch is
called. But I did not investigate this after my first
impression.
