[7u-dev] Request for approval for 8001208: Fix for KRB5CCNAME not complete

[Weijun Wang]

Hi All

This is a request to backport a jdk8 fix into jdk7u-dev.

The bug should be available at

    http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=8001208

Basically, it recognizes the KRB5CCNAME environment variable which can 
take the form of FILE:/tmp/ccache but has not removed the FILE: prefix 
before trying to read the file.

The fix is already included in jdk8 as:

    http://hg.openjdk.java.net/jdk8/tl/jdk/rev/a1e77f7ed52b
    Reviewed-by: xuelei

The patch for jdk7u-dev is identical to the one in jdk8.

The fix is low-risk, and isolated. An existing regression test is 
enhanced to confirm the fix. Existing tests also run fine.

Thanks
Weijun
