      Description

      Since the upgrade to Jenkins 1.609.1 (LTS) Jenkins needs significantly more memory parsing the JUnit results. We have slaves running with 512MB heap and there were no problems parsing all results in the previous version. Right after the update they are not not able to parse the same results with 1.5GB! I also checked and the largest XML result file is 17MB (and we don't keep large stdout/stderr). This looks like a serious regression in this version of Jenkins.
      Here's the relevant stack trace:
