GenericKeyedObjectPool.borrowObject does not invalidate object if
validateObject fails
--------------------------------------------------------------------------------------
Key: POOL-163
URL: https://issues.apache.org/jira/browse/POOL-163
Project: Commons Pool
Issue Type: Bug
Affects Versions: 1.5.4
Environment: Windows, java version "1.6.0_06", Torque 3.3 (DBCP 1.4,
jTDS 1.2.5)
Reporter: Gabor Horvath
GenericKeyedObjectPool.borrowObject does not invalidate object if
validateObject fails (line ~1200). I guess invalidation would be needed for
objects which are not newly created (newlyCreated flag in the code).
Scenario:
1.) DB connection put into pool
2.) Attempt to reuse connection (borrowObject)
3.) Test on borrow (executing simple SQL query) fails: DB connection closed on
jTDS level but connection remains in the pool
4.) Subsequent attempts to reuse the connection causes "java.sql.SQLException:
Invalid state, the Connection object is closed"
