The only thing I'm aware of is this supportpac:
http://www-01.ibm.com/support/docview.wss?rs=171&q1=xa03&uid=swg24012060&loc=en_US&cs=utf-8&lang=en
It only does a very narrow analysis looking for one particular problem and is somewhat outdated so I'm not sure how much use this will be.
I'd suggest that asking for static analysis tools would make a great "Request For Enhancement" (http://www.ibm.com/developerworks/rfe/?PROD_ID=532)
Of course the toolkit itself does provide some analysis during building of the project but I gather you're looking for something more substantial.
