Bug 68379

NB 5.0 200511091047
JDK 1.5.0_05

Sometimes the lock for web.xml is not released. Any further changes cannot be done.

Steps to reproduce:
1) create new webapp
2) create new servlet, filter or listener
-> it is added to web.xml but in the console there is:
java.lang.Exception: Not released lock for file: C:\Documents and
Settings\jp159440\WebApplication11\web\WEB-INF\web.xml (traped in finalizer)
-> from this moment any changes can not be done (manual or in the editor),
creating new servlet/listener/filter causes poping up of the warning message.

java.lang.Exception: Not released lock for file: C:\Documents and 

Settings\jp159440\WebApplication11\web\WEB-INF\web.xml (traped in finalizer)
