[jcifs] DeadLock - jcifs/smb/SmbTransport

[Roque]

Hi, I´m using jcifs1.2.9 for NTLM HTTP filter, and I´m getting a big number
of deadlock´s at application server  .

I found one post in (2006) almost similar to my problem, but can´t confirm
that the problem has been resolved, I would like to know if the problem as
been fix, and if not , can you please point me to possible fix to the
problem. 

Any help is appreciate, 
thank you Roque
