Hi all,

I have an application that is starting a thread that starts a jetty server with an rwt-application inside and stops it after a while. I see the following behavior:

When jetty is stopped I get an exception that some files inside the rwt-resource directory could not be deleted:
2013-09-11 13:26:10.870:WARN:oejuc.AbstractLifeCycle:FAILED org.eclipse.jetty.server.Server@73415727: java.lang.IllegalStateException: Could not delete: C:\Users\Hantschel\workspace\rwt-resource-test\rwt-resources\rap-client.js

When I now create a new jetty and start it with the RWT-App I get the following exception and the RWT-App does not work any more ('503 Service Unavailable' Error):

It looks like the file is somehow still open and can't be deleted because of that.

Any help would be appreciated.

thanks, Ralf

Hi all,

I have created a small Eclipse project where it's possible to reproduce the issue.
When you start it you can open the ui under 
localhost:7070/Example
.

The application starts a jetty. Runs it for 10 seconds and stops it. Then it creates a new jetty and starts it again. To reproduce the issue please open a browser and show the ui. After the jetty has been restartet refresh the browser. On my machine I have to do this 3-4 times until I get the HTTP 503 Error. (Exception on context init is thrown in this case).

Hope someone can help.

regards, Ralf

PS: I have compressed the Web folder in a separate bunch of zip files. Please copy it into the project directory or use the jars you have available on your system.
