Push request: 7043737: klist does not detect non-existing keytab

Hi All

This is a request to backport a jdk8 fix into jdk7u2 b02.

CR: 7043737: klist does not detect non-existing keytab
Weblink: http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=7043737

Description:

In JDK7 we support "dynamic" Kerberos keytabs so that a keytab can be
empty or missing when app starts. Unfortunately, the ktab tool also
reports no error or warning when keytab is missing. This behavior is
different from old JDK and ktab tools from other vendors. The fix brings
the old behavior back.

The fix is already included in jdk8 as:

The patch for jdk7u2 is identical to the one in jdk8.

I intend to push it to

    ssh://hg.openjdk.java.net/jdk7u/jdk7u-dev-gate/jdk

Thanks
