1.9 JavaHL memory leak in ISVNRemote#status

Attached example performs an endless series of remote status against the
Subversion repository. When invoked with -Xmx24M, the VM will run out of
memory soon. Monitoring with jvisualvm shows that the used heap size
constantly grows. Monitoring with the Task Manager shows that the
allocated memory grows even more (significantly). Looks like a memory
leak, for which a large amount of native memory is involved, too.

Tested on Windows 8.1 with almost latest Subversion 1.9 JavaHL builds.
