[8u-dev] Request for approval: 8036971: krb5.conf does not accept directive lines before the first section

[Wang Weijun]

Hi All 

This is a request to backport a jdk9 fix into jdk8u-dev. 

8036971: krb5.conf does not accept directive lines before the first section

   https://bugs.openjdk.java.net/browse/JDK-8036971

The fix ignores unsupported directive lines (Ex, include) before any section in a krb5.conf file.

It is already included in jdk9 as: 

   http://hg.openjdk.java.net/jdk9/dev/jdk/rev/74ee60cf6174 

The review thread was 

   http://mail.openjdk.java.net/pipermail/security-dev/2014-March/010282.html

The patch for jdk8u-dev is identical to the one in jdk9.

The fix is low-risk, and isolated. new regression test added. Existing tests also run fine. 

Thanks 
Weijun
