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.
