    • Jenkins 1.523, port-allocator 1.6

      I'm assigning one port in configuration, called Arquillian. When using version 1.6 of port allocator, only one job starts execution and others are blocked by it.

      Thread dump had following:

      After adding https://github.com/jenkinsci/jenkins/pull/853, log got following lines:

      Jul 17, 2013 7:23:45 AM hudson.model.ResourceList _getConflict
INFO: Collision with standalone port ARQUILLIAN(1)=1 and standalone port ARQUILLIAN(1)

      Downgrading to version 1.5 of port allocator solved the problem
