                 URL: https://issues.apache.org/jira/browse/DERBY-4863
             Project: Derby
          Issue Type: Bug
          Components: Network Server
    Affects Versions: 10.6.2.1
         Environment: windows 7, jdk 1.5.0_22, derby 10.6.2.1
            Reporter: Florin Herinean


Derby update statements do not timeout until the (write) locks are released.

The scenario involves 2 threads starting 2 separate transactions/connections, each of them attempting to update the same row. The first thread starts the transaction, locks the row (via update) then waits 40 seconds. The second thread is started 5 seconds later and it has a 5 seconds timeout set on the statement. Upon attempting to update the same row as the first thread, it times out after 35 seconds (40 - 5) and not after the expected 5 seconds as specified in the statement timeout.

A test case is attached.

Oracle and DB2 behaves as expected.
