New jre layout broke Maven and Ant

[Henri Gomez]

Hi guys

I got various reports on openjdk-osx-build about failure to detect tools.jar :

http://code.google.com/p/openjdk-osx-build/issues/detail?id=22
http://code.google.com/p/openjdk-osx-build/issues/detail?id=23

As a temporary fix, I'll add a symlink in package

ln -s lib/tools.jar 1.7.0.jre/Contents/Home/lib/tools.jar

tools.jar is under JAVA_HOME/lib for both OS/X and Linux version.

Could it be something related to JRE_HOME/JAVA_HOME ?
