Memory leak with org.tmatesoft.svn

Rate this Message:
It appears the org.tmatesoft.svn package causes a memory leak. All
SVNClientManager instances incl. all referenced objects stay in memory even after all references by our application have been garbage collected. Our code basically looks like this: ISVNOptions options = SVNWCUtil.createDefaultOptions(true); options.setAuthStorageEnabled(false); SVNClientManager clientManager = SVNClientManager.newInstance(options, new BasicAuthenticationManager(user, password)); SVNRepository svnRepository = clientManager.createRepository(SVNURL.parseURIDecoded(url), false); SVNLogClient logClient = clientManager.getLogClient(); logClient.doLog(...); How can we fix the problem? We use svnkit-1.1.4.3622.
