I saw this exception in eclipse log after installation of everything from RH Central. I see that you have met this problem in JBDS-2666 and jira was closed as 'can't reproduce'.
It seems that this error is reproducable using automated test of installation from RH Central [1], see builds 18-20, choose OS and open eclipse-log-startAfterInstall.log. This error is in all builds and on all systems.
