Stream passed out to user does not heed close, allowing reads after next
ResultSet#getXXX
-----------------------------------------------------------------------------------------
Key: DERBY-4521
URL: https://issues.apache.org/jira/browse/DERBY-4521
Project: Derby
Issue Type: Bug
Components: JDBC
Reporter: Dag H. Wanvik
Priority: Minor
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.
