Could not delete rwt-resources on shutdown [message #1106669]

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

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.

It seems to be generic Windows message. It is usually caused by antivirus.
Please disable your antivirus program or add the files mentioned in the trace to exception rules and try again.
