OpenJDK 7 for PPC Macs under OS X 10.5?

[Bill Connelly]

Can you tell me if this is valid today? If this is not the proper  
Forum for this question, can you point me to one that is? Thanks.

I was hoping for a version of Java greater than 1.5 for my PPC Mac (A  
Digital Audio Dual 533 G4 running Leopard 10.5.8).

I found this version of OpenJDK 1.7 which they say is for PPC Macs:

32-bit OpenJDK 7 Beta 1 for Mac OS X 10.5 PowerPC (Beta Release):  
openjdk7-macppc-2009-12-16-b4.tar.bz2

on http://landonf.bikemonkey.org/static/soylatte/

And this is what I get as echo $PATH and java -version in Terminal,  
after downloading, decompressing, placing it in my Users Library, and  
adding it to my PATH:

Acoustic-Piano-Mac-3:~ moonstoneartstudio$ echo $PATH
/opt/local/bin:/opt/local/sbin:/Users/moonstoneartstudio/Library/ 
openjdk7-macppc-2009-12-16-b4/bin:/sw/bin:/sw/sbin:/usr/bin:/bin:/usr/ 
sbin:/sbin:/usr/local/bin:/usr/X11/bin


Acoustic-Piano-Mac-3:~ moonstoneartstudio$ java -version
openjdk version "1.7.0-internal"
OpenJDK Runtime Environment (build 1.7.0-internal- 
landonf_2009_12_16_12_54-b00)
OpenJDK Zero VM (build 17.0-b05, interpreted mode)

But it doesn't show up in the Java Preferences.app window ... just 1.5  
and 1.4, and when I try to run an application requiring Java, such as  
PS3 Media Server, it still says there's no Java version >= 1.6.

Know what I'm missing? It's a Developer package, and hasn't been  
turned on, even though its in the PATH?

I did try a Safe Boot and Restart to rebuild caches to no avail.
