Subject: [pgjdbc/pgjdbc] PR #3778: fix: avoid IllegalStateException: Timer already cancelled  when StatementCancelTimerTask.run throws a runtime error
Date: Wed, 20 Aug 2025 08:30:11 +0000
Message-ID: <[email protected]> (raw)

Previously, StatementCancelTimerTask might propagate runtime errors to java.util.Timer which causes the Timer to cancel itself. We don't want that behavior, so we should avoid throwing errors from TimerTask implementations.

Note statement.cancelIfStillNeeded has already been ignoring SQLExceptions from statement.cancel() for quite a while, however, it did not ignore runtime errors.

Fixes https://github.com/pgjdbc/pgjdbc/issues/3530
