It could be, or it could just be that this is the drop that overflows
the bucket. I need more information.

How many rows are you fetching? You are using a CachedRowSet, which
holds all rows fetched, including blob data, which means it can consume
a lot of memory.

Have you tried to create a heap dump (eg using
-XX:+HeapDumpOnOutOfMemoryError).

If possible, could you send me a (private) link to a memory dump so I
can take a look?
