I would have thought that the Oracle forum and support process would the best 
place to get detailed information about their implementation if you have 
performance issues with it. Aren't they giving support on Kodo now?

Getting an EXISTS clause generated from JDOQL would usually involve the use of 
the contains() or isEmpty() methods. 

If you deem that Oracle aren't serious about supporting their JDO 
implementation then DataNucleus is really what you should be trying, since we 
do treat JDO as a first class persistence specification ...
