Closed Hipapheralkus closed 5 years ago

Hi, maybe it's not connected, but I get Java exceptions when trying out on the new Burp 2:

@Hipapheralkus This type of error is usually due to a partial match or a false positive. If you know what URL/response caused the error I can try to track down which match rule is causing the error and "tune out" the false positive.

I think this is a duplicate of #72, which is now fixed by PR #83. Please let me know if you continue to get this error with the latest match rules.
