UpdateWorkingCopyPhaseTest fails in continuum-release, file url is incorrect

The error is: "Unable to open an ra_local session to URL".
This can be corrected by adding a third "/" to the scm URL
in line 114 (Revision 928595) to org.apache.maven.continuum.release.phase.UpdateWorkingCopyPhaseTest
so that the URL reads:
"scm:svn:file:///" + projectUrl
There is an empty hostname, so the third slash seems to be required,
See
http://svnbook.red-bean.com/nightly/en/svn.basic.in-action.html#svn.advanced.reposurls
for reference.
