other builds also have this problem:

https://hudson.eclipse.org/hudson/view/Tycho%20+%20Maven/job/tycho-soa.sca.trunk-indigo/scmPollLog/?

This is the Hudson issue:

http://issues.hudson-ci.org/browse/HUDSON-8982
"This issue is fixed in subversion plugin ver. 2.2.0_1, please verify the version of subversion plugin installed on your system."

Please could we upgrade to 2.2.0_1 or later to fix the issue at hudson.eclipse.org
