bmsubmit is not working due to Bad Request 400. Why?

Question

I am using byteman 4.0.17. Installing byteman succeeded. Using bmsubmit.sh tool is throwing an error.

$ byteman-download-4.0.17/bin/bmsubmit.sh -y
Failed to process request: java.lang.Exception: Invalid name/value pair in line [HTTP/1.1 400 Bad Request]. Full response below:

Also when I try to submit a rule I get an error.

$ byteman-download-4.0.17/bin/bmsubmit.sh -l /mnt/jenkins/FileDescriptorLeak.btm

Am I doing something wrong here ?

IF TRUE
DO traceStack("*** Called init in thread " + Thread.currentThread().getName() + "\n", 30)

Answer 1

The solution to the issue is to define an unused port when using the bminstall command. With the -p flag.
