I think I've found a bug in the singlevm PersistenceBrokerImpl. The problem
occurs when the target of a many-to-many relationship is a proxied class and the
indirection table is implicit. In 0.9.7 I get exceptions like the following:
[org.apache.ojb.odmg.ObjectEnvelopeTable] ERROR: Commit on object level failed

It appears that the problem is that storeMtoNImplementor does not check for
otherObj being a proxy and does not retrieve its realSubject. I added this
code:
if (otherObj instanceof VirtualProxy)
{
otherObj = ((VirtualProxy) otherObj).getRealSubject();
}
// same for dynamic Proxies
else if (Proxy.isProxyClass(otherObj.getClass()))
{
IndirectionHandler handler = (IndirectionHandler)
Proxy.getInvocationHandler(otherObj);
otherObj = handler.getRealSubject();
}
... before the declaration of otherCld, and the problem went away. Anybody want
to comment and/or commit a fix?
thanks,
