[jira] Created: (CAY-1513) Deadlock in PoolManager
Deadlock in PoolManager
-----------------------
Key: CAY-1513
URL: https://issues.apache.org/jira/browse/CAY-1513
Project: Cayenne
Issue Type: Bug
Components: Core Library
Affects Versions: 3.0
Environment: Linux
Reporter: Laurent Marchal
I'm using cayenne 3.0 ans I'm experiencing a deadlock when I exit my application. I call PoolManager.dispose() to disconnect all connections, but it seems if at the same time a pooled connection is returned to the pool then it deadlocks.
Here is the deadlock as detected by the java console.
Name: Worker-2
State: BLOCKED on com.sma.core.net.OpconPoolManager@197871d owned by: main
Total blocked: 327 Total waited: 475
Stack trace:
