Thanks for letting us know about this. Can you confirm what versions of Java and Jython you are using?

I believe this may be related to this issue:

- https://jira.mongodb.org/browse/JAVA-2559

What I recommend you do is install Burp using the Burp Platform Installer. This includes a version of Java we know works well with Burp. Also, we recommend Jython 2.7.0 – that has been stable and reliable for us.

Please let us know if you need any further assistance.
