Hi!
JBoss maps all invocations to EJBLocalObject.equals(Object o) to isIdentical(EJBLocalObject a) resp. org.jboss.ejb.plugins.local.LocalProxy.isIdentical(Object a, Object b), which assumes the object a to be an EJBLocalObject (cast!). In the case the original invocation comes from isIdentical(...), this is no problem, but if you drop EJBs and other things in a context, where the equals(Object o) method is invoked with real-world (non-EJB) object you get a crash. "Hashtable.contains(Object o)" is such a context,
where the EJBLocalObject.equals() method is invoked with arguments possibly different than EJBLocalObjects.

FIX (for local object only):
is just two lines in org/jboss/ejb/plugins/local/LocalProxy.java
/**
* Test the identitiy of an EJBObject.
*
* @param a EJBObject.
* @param b Object to test identity with.
* @return True if objects are identical.
*
* @throws ClassCastException Not an EJBObject instance.
*/
Boolean isIdentical(final Object a, final Object b)
{
if (!(a instanceof EJBLocalObject)) // one
return Boolean.FALSE; // two
final EJBLocalObject ejb = (EJBLocalObject)a;
Boolean isIdentical = Boolean.FALSE;
if( ejb != null )
{
final Object pk = ejb.getPrimaryKey();
isIdentical = new Boolean(pk.equals(b));
}
return isIdentical;
}
