We've set up SVNKit in our Jenkins instance to use JNA to collect credentials for SVN access by setting -Dsvnkit.http.ntlm=jna in jenkins.xml. This has been working perfectly until we tried to upgrade Jenkins to 1.586, when the Jenkins JNA implementation was bumped to jna 4.10. After that, we get an "E200015: No credential to try." error.
The last working version was Jenkins 1.585 and subversion plugin 2.4.5. If I upgrade any of them, we get the error.
