[JIRA] [port-allocator] (JENKINS-18786) Port allocation blocks all jobs from executing

Tue, 16 Jul 2013 22:03:07 -0700

Issue Type: Bug Bug
Assignee: ramapulavarthi
Components: port-allocator
Created: 17/Jul/13 5:01 AM
Description:

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:
