Description Rob Stryker

1. Create a dynamic web project, make sure some libs live inside WEB-INF/lib, physically inside the folder. 
2. Deploy the project to a JBoss AS, even using a generic server
3. Start the server
4. Remove any JAR from WEB-INF/lib folder
5. I get a lot of IOExceptions and the project is not built anymore
6. Stopping server/re-building project doesn't help. Lots of JDT code fails with errors
7. Only restarting Eclipse can help.

I suspect this may be because of the murky relationship between things that live inside web-inf/lib, and the classpath containers that manage them and look for them on occasion. 

Here are the exceptions (a lot of them):

Rob, everything here looks like just JDT code.  I am assigning this to you for further investigation... unless you find otherwise, you probably want to send this down to the JDT team for their investigation.
