Kevin Sutter commented on OPENJPA-555:
--------------------------------------
Catalina, is the check for a null databaseProductName sufficient? I mean, if
the DB2Dictionary has not been initialized, then your changed methods will now
be returning "false". But, we very well could be using one of the versions of
DB2. We just haven't initialized and, thus, we don't know whether we're using
one of the desired versions of DB2. Especially since we're dealing with the
MappingTool. I would assume that we make some decisions on how to perform the
mapping based on the version of DB2 that we're using. Otherwise, why would
these methods be invoked in the first place? From the text in the forum, it
sounds like with this change, the index won't automatically be created if we
fall into this scenario. This just doesn't sound like the right fix. Please
justify. Thanks.
