New drag and drop install for universal build is broken.

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Download OpenJDK-OSX-1.7-universal-20110920.dmg
2. Drag 1.7.0.jdk to folder as instructed
3. Set JAVA_HOME and PATH to that jdk
4. Try to build a java project.

I'm trying to build jruby but ant doesn't work with the latest build of 
universal.

A bit more information from me, one of the JRuby guys...

This definitely looks like some sort of mismatch between the new builds and 
ant. Ant will try to determine the proper location of tools.jar based on 
JAVA_HOME and other env stuff. This worked fine in previous builds that had a 
pkg installer, but the new builds seem to be confusing ant into trying to stick 
the weird JRE path on the end of the JDK path.

If our theory is right, this should break any ant build, not just JRuby. We 
don't do anything special in our build script.

Sorry, I didn't figure this ticket before.

I tried also 

{{{
ant
Unable to locate tools.jar. Expected to find it in 
/Library/Java/JavaVirtualMachines/1.7.0.jdk/Contents/Home/1.7.0.jre/Contents/Hom
e/lib/tools.jar
}}}

Ant like Maven are puzzled by the the new 1.7.0.jre subdir added by Mike at the 
same time we change our deployment procedure.

I'll try a fix on package side until macosx-port fix that.

On Apple 1.6.x JVM javac is found under JAVA_HOME/Contents/Classes/classes.jar

For OpenJDK it's now here JAVA_HOME/lib/tools.jar (both for OS/X and Linux)

As a tempory fix (while discussing with OpenJDK team),  I'll add the following 
in package process :

ln -s /Library/Java/JavaVirtualMachines/1.7.0.jdk/Contents/Home/lib/tools.jar 
/Library/Java/JavaVirtualMachines/1.7.0.jdk/Contents/Home/1.7.0.jre/Contents/Hom
e/lib/tools.jar

May be a problem in Ant or JRE_HOME/JAVA_HOME.

Added a symlink between lib/tools.jar and jre/lib/tools.jar in 
OpenJDK-OSX-1.7-universal-b210-20110930.dmg to temporary fix this issue. 

JIRA ticket to macosxport to be created
