Can't fix Java under Leopard - help!

Question

I was using Tiger with Java 1.6 SE set as the default. I then upgraded to Leopard and have found that 1.6 is not supported (ok, in my haste, I didn't research this properly).
However, now, I'm stuck because I can't switch the default back to 1.5. When I launch Java Preferences, I get the following error:
Dyld Error Message:
Symbol not found: _CTFontGetGraphicsFont
Referenced from: /System/Library/Frameworks/JavaVM.framework/Versions/1.6.0/Libraries/libawt.jni lib
Expected in: /System/Library/Frameworks/ApplicationServices.framework/Versions/A/Application Services
But this is a Unix system, isn't it... so there must be a file somewhere that I can edit to fix all of this?
Also, how can I uninstall Java 1.6 SE?

Hmmm.. I see what you're getting at but in fact the CurrentJDK folder is already linked to the 1.5 folder. When I run java -version it shows as version 1.6. So...
$ ls -l `which java`
lrwxr-xr-x 1 root wheel 74 30 Oct 23:22 /usr/bin/java -> /System/Library/Frameworks/JavaVM.framework/Versions/Current/Commands/java
And in the Versions directory there's this odd directory called simply "A", which Current points to:
Mac:Versions Rick$ ls -l
total 56
lrwxr-xr-x 1 root wheel 5 30 Oct 23:22 1.3 -> 1.3.1
drwxr-xr-x 3 root wheel 102 29 Sep 07:53 1.3.1
lrwxr-xr-x 1 root wheel 5 30 Oct 23:23 1.4 -> 1.4.2
lrwxr-xr-x 1 root wheel 3 30 Oct 23:22 1.4.1 -> 1.4
drwxr-xr-x@ 8 root wheel 272 8 Apr 2005 1.4.2
lrwxr-xr-x 1 root wheel 5 30 Oct 23:23 1.5 -> 1.5.0
drwxr-xr-x 8 root wheel 272 21 Nov 2005 1.5.0
lrwxr-xr-x 1 root wheel 5 20 Sep 20:43 1.6 -> 1.6.0
drwxr-xr-x 8 root wheel 272 21 Aug 08:16 1.6.0
drwxr-xr-x@ 7 root wheel 238 30 Oct 23:23 A
lrwxr-xr-x 1 root wheel 1 30 Oct 23:23 Current -> A
lrwxr-xr-x 1 root wheel 3 30 Oct 23:22 CurrentJDK -> 1.5
The "A" directory only contains JRE 1.6 as far as I can tell.
