Debugging webapps broke - Unable to set breakpoints

Hi,

I am unable to set breakpoints when debugging webapps I get a UnSupportedOperation exception. Attaching a simple web-app (attached to the issue mentioned below) project try setting a break point after executing one request from the browser.

Can someone please take a look at this?

Thanks,
