It seems this is documented incompatibility resulting from a necessary fix (the alternative was incorrect data retrieval). Perhaps Kristian can add more details.

I don't think it is the right fix to apply - restrict user from multiple calls to getObject(int) if it is BLOB or CLOB. I've never seen this in other dbs, well in Derby also :) Maybe we could think on how to gracefully handle this?
