java.library.path fix for MacOS X (7145798)

I agree 100%. And since it is already included in the JDK, it seems silly to require users to copy it to the Java directory.

Right. I was thinking that we could have the launcher app set the working directory to the bundle root at startup. Then you could add this to the build script to add tools.jar (or anything else within the bundle) to the class path:

<option value="-classpath Contents/PlugIns/1.7.0.jdk/Contents/Home/lib/tools.jar"/>
