ConcurrentModificationException in ConnectionTracking with Daytrader 1.2 under
load
-----------------------------------------------------------------------------------
Key: GERONIMO-2708
URL: https://issues.apache.org/jira/browse/GERONIMO-2708
Project: Geronimo
Issue Type: Bug
Security Level: public (Regular issues)
Components: connector
Affects Versions: 1.2
Environment: Geronimo 1.2 from geronimo/sever/branches/1.2 (01/04/2007)
RHEL 4
SUN 1.5.0_10 JDK
Reporter: Christopher James Blythe
Looks like are some concurrency issues with Connection Tracking in Geronimo 1.2.
- Built Geronimo from geronimo/sever/branches/1.2 (01/04/2007)
- Deployed Daytrader (built from geronimo/daytrader/branches/1.2)
- Stressed "EJB" and "Session to JDBC" mode with multiple clients using load
driver
Both tests resulted in the following exception when more than 1 client was
driven.
NOTE: I went back and double checked on Geronimo 1.1.1 and this does not occur.
