how to do svn merge with 2 URLs and destination path

Hi,

In SVNKit, we have a function of doMerge like
void doMerge(SVNURL url1, SVNRevision revision1, SVNURL url2, SVNRevision revision2, File dstPath, SVNDepth depth, boolean useAncestry, boolean force, boolean dryRun, boolean recordOnly)


But when I use this its not working but from the SVN command line its working...Regarding this some unanswered question highlights this as a bug http://www.nabble.com/Merge-and-Conflict-Question-td10262038.html

Is this a bug in svnkit?? If not please advice me how to use this....
