Activate debugging for the jdbc connection ... that will show you the
access paths that are generating in the jdbc server joblog.

To activate debugging ... add 'server trace=44' to your JDBC url.

Then find the appropriate server job and look at the joblog.

You'll find the query optimizer diagnostics pretty helpful.
