Multiple extensions give me a java error

Gabi | Last updated: Nov 03, 2022 09:13AM UTC

Hi all, I use the latest version of Burp Professional on macOS Ventura. I notice that since yesterday some extensions don't work anymore and give me this error: Header Analyzer: at java.base/java.util.concurrent.FutureTask.run(FutureTask.java:264) at

Hi. Is this just happening for Python-based extensions? Does this issue occur when you try to use the extension or when you load the extension into Burp?

Hi, For example this error is made by BurpBounty extension: And the errors come when I try to use these extensions java.lang.UnsupportedOperationException: Not supported yet. at burpbountypro.BurpBountyExtension.scopeChanged(BurpBountyExtension.java) at burp.tj8.lambda$registerScopeChangeListener$8(Unknown Source) at java.base/jdk.internal.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at java.base/jdk.internal.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:77) at java.base/jdk.internal.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:43) at java.base/java.lang.reflect.Method.invoke(Method.java:568) at burp.q0t.invoke(Unknown Source) at jdk.proxy2/jdk.proxy2.$Proxy29.scopeChanged(Unknown Source) at burp.qoy.run(Unknown Source) at java.base/java.util.concurrent.Executors$RunnableAdapter.call(Executors.java:539) at java.base/java.util.concurrent.FutureTask.run(FutureTask.java:264) at java.base/java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1136) at java.base/java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:635) at java.base/java.lang.Thread.run(Thread.java:833) java.lang.UnsupportedOperationException: Not supported yet. at burpbountypro.BurpBountyExtension.scopeChanged(BurpBountyExtension.java) at burp.tj8.lambda$registerScopeChangeListener$8(Unknown Source) at java.base/jdk.internal.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at java.base/jdk.internal.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:77) at java.base/jdk.internal.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:43) at java.base/java.lang.reflect.Method.invoke(Method.java:568) at burp.q0t.invoke(Unknown Source) at jdk.proxy2/jdk.proxy2.$Proxy29.scopeChanged(Unknown Source) at burp.qoy.run(Unknown Source) at java.base/java.util.concurrent.Executors$RunnableAdapter.call(Executors.java:539) at java.base/java.util.concurrent.FutureTask.run(FutureTask.java:264) at java.base/java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1136) at java.base/java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:635) at java.base/java.lang.Thread.run(Thread.java:833)

It seems that the problem is with these extensions, because other colleagues in the company are experiencing exactly the same errors. And errors started to appear after the last Burp update

I can confirm that even using Burp v2022.9.4 from Windows 10 gives me the same error from Headers Analyzer Extension: at java.base/java.lang.Thread.run(Thread.java:833) java.lang.NullPointerException: Cannot read the array length because "array" is null at java.base/java.util.Arrays.stream(Arrays.java:5428) at burp.d61.requestResponses(Unknown Source) at burp.a_w.getHttpMessages(Unknown Source) at burp.at6.<init>(Unknown Source) at burp.s_.run(Unknown Source) at java.base/java.util.concurrent.Executors$RunnableAdapter.call(Executors.java:539) at java.base/java.util.concurrent.FutureTask.run(FutureTask.java:264) at java.base/java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1136) at java.base/java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:635) at java.base/java.lang.Thread.run(Thread.java:833) java.lang.NullPointerException java.lang.NullPointerException java.lang.NullPointerException java.lang.NullPointerException java.lang.NullPointerException java.lang.NullPointerException java.lang.NullPointerException java.lang.NullPointerException java.lang.NullPointerException java.lang.NullPointerException java.lang.NullPointerException java.lang.NullPointerException java.lang.NullPointerException

Doesn't anyone have any answers as to why this is happening and how to fix it? I can tell you two more extensions in the Bapp Store no longer work and give a lot of errors.

Hi. Can you drop us an email at support@portswigger.net with your diagnostics information? You can find this by going to "Help > Diagnostics" in Burp. Can you confirm that you are seeing this issue with our latest release, v2022.9.5? We've tried to replicate your issue but have not been successful.

Gabi | Last updated: Nov 10, 2022 08:15AM UTC

Back to v2022.8.5 and everything is working properly again
