NullPointerException with Burp v2.0.17 and 1.7.37

[felmoltor]

Hello,

Installed blazer extension(v0.3 - 01 Feb 2017) for Burp v2.017 but whenever I try to use it from the proxy history, the extension returns the following error. I tryed to use the tree options provided, AMF Testing, AMF2XML and Enable/Disable Sec manager:

java.lang.NullPointerException at burp.CustomMenuItem.menuItemClicked(BurpExtender.java:153) at burp.cta.run(Unknown Source) at java.base/java.util.concurrent.Executors$RunnableAdapter.call(Executors.java:515) at java.base/java.util.concurrent.FutureTask.run(FutureTask.java:264) at java.base/java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1128) at java.base/java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:628) at java.base/java.lang.Thread.run(Thread.java:834)

Is this a known issue?

Thank you.

EDIT: Tested with 1.7.37 Pro and a similar error pop-ups in the extension output:

java.lang.NullPointerException at burp.CustomMenuItem.menuItemClicked(BurpExtender.java:153) at burp.he.run(Unknown Source) at java.lang.Thread.run(Thread.java:748)

This extension is no longer supported, and it works on Burp 1.7.x only. You can download the 1.7 version from Portswigger website.
