ESB tests fail when run outside all-in-one collection of tests

I've created a new ESB-only build job [0].

[0] http://hudson.qa.jboss.com/hudson/job/jbosstools-3.2_trunk.component--esb/

Unfortunately, it's not passing all its tests (unlike when run in the all-in-one job) [1].

[1] http://hudson.qa.jboss.com/hudson/view/DevStudio_Trunk/job/jbosstools-3.2_trunk.tests/lastCompletedBuild/testReport/org.jboss.tools.esb.project.core.test/ESBProjectAllTests/

Here's a snippet of the errors [2].
