Kathey Marsden commented on DERBY-4521:
---------------------------------------

Labeled derby_backport_reject_10_8. Since it is a behavior change prohibiting an operation, probably not suitable for a maintenance release.

> This was discovered investigating DERBY-4477 using the repro for DERBY-3646, which erroneously
> tries to keep two streams passed out via REsultSet#getBinaryStream open at the same time. This is prohibited by JDBC [1],
> but Derby allows it for non-materialized streams because the close call on the passed out stream (performed by EmbedResultSet#closeCurrentStream at the time of the next getXXX) is not heed by the underlying Derby stream.
