[2.3 Branch] Fix JAWT regression in OpenJDK7

[Omair Majid]

Hi,

There was a change in behaviour in how the JRE loaded libjawt.so between
OpenJDK6 and OpenJDK7, causing a number of programs to stop working. The
fix for this is upstream:

http://hg.openjdk.java.net/jdk8/awt/jdk/rev/f003387c33ad

More details about the issue are available at:
http://mail.openjdk.java.net/pipermail/build-dev/2012-July/006486.html

May I backport this to the IcedTea7 2.3 branch?

Thanks,
Omair
