[jcifs] Blocking on lock for Dfs object?

[Bryan Klopfenstein]

Hi all, we are encountering lock issues with Dfs object that are nearly
constant since Jan 5 with a system that has been working for two years.
Stack trace of stuck thread in weblogic below, showing wait on lock on Dfs
object. Any ideas on where we hunt for cause?

Do you (or anyone) know of any plans for these patches to be combined into
a new general release?

Hi Bryan,

It's on the TODO list but there is no ETA.
