Leak in client if ResultSet not closed
--------------------------------------
Key: DERBY-3316
URL: https://issues.apache.org/jira/browse/DERBY-3316
Project: Derby
Issue Type: Bug
Components: Network Client
Affects Versions: 10.3.2.1, 10.2.1.6, 10.4.0.0
Reporter: Kathey Marsden
If I run the attached program RepeatStatement.java with 32M of heap,
I will get an OutOfMemory error in the client.
java -Xmx32M RepeatStatement
Exception in thread "main" java.lang.OutOfMemoryError: Java heap space

If I close the ResultSet or Statement it does not leak.
This occurs on trunk and 10.2.1.6. It does however not run out of memory on
10.1.3.1, so appears to be a regression.
