[7u6] Request for approval for CR 7071907 JDK: Full Debug Symbols

[Daniel D. Daugherty]

Greetings,

This is a request to backport a JDK 8 fix into JDK 7u6:

7071907 4/4 JDK: Full Debug Symbols
http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=7071907

along with its follow on regression fix:

7160895 3/3 TEST_BUG: tools/launcher/VersionCheck.java attempts to 
launch .debuginfo
http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=7160895

The fixes have recently been pushed to JDK 8, as:

http://hg.openjdk.java.net/jdk8/tl/jdk/rev/d922195b678d
http://hg.openjdk.java.net/jdk8/tl/jdk/rev/70d82f2a6c11

and will be included in the JDK8-B36 T&L PIT snapshot.

These fixes have been reviewed on build-dev at openjdk.java.net:

http://mail.openjdk.java.net/pipermail/build-dev/2012-April/005944.html

and hotspot-dev at openjdk.java.net:

http://mail.openjdk.java.net/pipermail/hotspot-dev/2012-April/005616.html

and serviceability-dev at openjdk.java.net:

http://mail.openjdk.java.net/pipermail/serviceability-dev/2012-April/005720.html

The three review threads are slightly different because not all
comments were originally posted to all three aliases. I did try
to forward all such comments to all three aliases.

The JDK7u6 and JDK8 jdk repo patch files:
   - identical except for timestamps, some line numbers,
     and some context diff anchors
   - no content difference between JDK7u6 and JDK8
