Hi,

I would like to backport this fix from 8 to 7u.

https://bugs.openjdk.java.net/browse/JDK-7199674

The source code changes apply cleanly to 7u from the 8 changeset, 
however the makefile changes needed to be tweaked. 
makefiles/CompileNativeLibraries.gmk did not exist in 7, so equivalent 
changes are made in make/java/java/Makefile instead.

Since it's not a direct port of the 8 changes, my understanding is that 
the 7-specific changes should be reviewed.

7u40 webrev is here:
http://cr.openjdk.java.net/~bchristi/7199674/7u/webrev.0/

Again, the only difference from the 8 fix is in make/java/java/Makefile.


For reference:

* JDK 8 changeset:
