I have 5 jobs running on a slave sequentially. Using robot plugin I upload the reports from each of the jobs post build.

I see only one job is getting the results parsed whereas the 4 others are having issues with parsing the output.xml.

My earlier version of Jenkins and robot plugin were 2.19 and 1.6.4. I tried to downgrade the version of Jenkins since some other products jobs were working fine on Jenkins version 1.633 and Robot plugin 1.6.1 but still saw the same issue. I am pasting the stacktrace here. I enabled jenkins logging for robot-plugin but still didn't see any additional information which may help to debug. Can anybody help to know what is the issue here?
