A DESCRIPTION OF THE PROBLEM :
We are getting sporadic failures in SOAP requests. The underlying problem appears to be in the the new available method introduced in bug 8000410. It does not check if the serverSocket field is closed before calling getSoTimeout on it.

I'm not totally sure if this is actually a bug or due to misuse of HttpClient (it's being called by Apache CXF).

This never happened in 6.0.37.

REGRESSION.  Last worked in version 6u31
