Affects Version/s: 1.0, 1.0.1, 1.0.3, 1.0.4, 1.1.0, 1.1.1
Fix Version/s: 1.1.2
To reproduce the problem:
Create a WAR that contains a JAR that contains commons-logging.properties.
Deploy this WAR to TOMCAT 5.x
Try to redeploy it, it will fail
This is due to the fact that LogFactory uses url.openStream to open this file , thus URLConnection will use an internal cache and this will provoke a lock on the file from Window.
