[11u] RFR 6722928: Provide a default native GSS-API library on Windows

[Martin Balao]

Hi,

I'd like to request a review for the 11u backport of "6722928: Provide a
default native GSS-API library on Windows" [1].

Webrev.00

 * http://cr.openjdk.java.net/~mbalao/webrevs/6722928/6722928.webrev.11u.00

Conflicts:

 *
src/java.security.jgss/share/classes/sun/security/jgss/wrapper/SunNativeProvider.java
  * There is one hunk that does not apply cleanly because a line below
the one modified is changed by 8209416 [2].
   * 8209416 does not apply cleanly (8+ conflicts) and is not
fundamental to 6722928 as it's an enhancement related to obtaining
values from properties, while 6722928 is about using the native Windows
libraries for GSS.
  * This conflict has been solved by changing the hunk context to match
11u source code; there are no changes on the modified line itself.

Testing:

 * The main line patch does not include a regression test because of its
complexity (an Active Directory is needed). I manually tested a few
calls through the DLL bridge and observed no errors. Given that this is
a pluggable provider, the risk is low.

If this proposal is review-approved, I'll go through the CSR process and
request a 11u backport.

Followup bugs that will be proposed for 11u backporting:

Thanks,
Martin.-
