srinivas_pullaiahgari can you provide steps to reproduce, and/or the stacktrace in the logs? 

Steps to reproduce the issue:

2) you will get the above reported issue.

srinivas_pullaiahgari the stack trace for the issue is inside the Jenkins log file. The steps to reproduce the issue need to include enough details that someone else can duplicate the issue. If you can't provide enough details to allow someone else to duplicate the issue, then you need to provide more details about your Jenkins environment so that others might guess what is different in your environment compared to working environments. See "How to report an issue" for the type of information that is needed.

srinivas_pullaiahgari please provide a full list of plugins:

timja I assumed when srinivas_pullaiahgari said that the problem was not related to tables to divs because it is on Jenkins 2.254. Was that a typographical error in the initial report? Should it have been 2.264 rather than 2.254 srinivas_pullaiahgari?

Ah right my mistake
