[JIRA] [ws-cleanup] (JENKINS-23693) Cannot delete workspace

Mon, 25 Aug 2014 19:29:43 -0700

We also hit the issue in version 0.22. I don't have a case to reproduce, but referring to the following stacktrace, I think it's required to check for null before calling get(command) on EnvVars

SEVERE: null
java.lang.NullPointerException

I will propose a PR with the null check if it works.
