I have installed the EnvInject plugin. Currently it is not enabled in any job.

In a free-style job (JUnit/Ant) the following exception is thrown always:

INFO: my_job_unit_tests #181 main build action completed: SUCCESS
11.01.2012 11:01:44 hudson.model.Executor run
SEVERE: Executor threw an exception
