Hi Sajith, Try setting the serialVersionUID manually without relying on that generated automatically by Java. I.e. set a value to a static final long field in your SiddhiBolt.
Restarting the supervisor might also do the trick (after clearing the local directory). Your supervisor seems to be hung up on the older version of your jar. Cheers, Kosala.
