      Lockable Resources Plugin 2.5

      I got this ConcurrentModificationException when using "lock" step for several pipelines running on the same master at the same time. I believe it can happen when new locks are being created while the list of locks is being looped through.

          Getting the same issue for Jenkins 2.190.2 and Lockable Resources Plugin2.7.

          Has happened a few times and seems to be happening when many jobs have started at the same time and they are all trying to use the lock step.

          Should be fixed in the next release, see https://github.com/jenkinsci/lockable-resources-plugin/pull/191
