There are several factors that go into determining which VM runs in OS
X ... It's not just a matter of the symlink. Your java preference
settings can change which version it uses also, the Info.plist of a
launcher can change it, etc. So the actual symlink for "A" is the
same, but the java executable in /usr/bin/java selects which framework
to bind to using different (non-obvious) criteria.

I figured out that my problem is that /System/Library/Frameworks/
JavaVM.framework/Versions/Current is linked to /System/Library/
Frameworks/JavaVM.framework/Versions/A. Somehow the java in "A" can
change depending on which user invokes it. I have no clue how this
works, but I changed Current to point to 1.6.
Is this going to cause me any problems? Is there a better way to do
this? i.e. set a system variable to make "A" use 1.6?

I am currently having trouble deploying an application under
JavaMonitor because of "incompatible version" errors on a class
file. When I launch the app as admin, the app launches fine. I
finally traced the problem to the fact that when the appserver user
invokes java it is 1.5 but when admin does it is 1.6. See the
terminal transcript below.
app2:Logs admin$ sudo -u appserver /usr/bin/java -version
java version "1.5.0_19"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.5.0_19-
b02-304)
Java HotSpot(TM) Server VM (build 1.5.0_19-137, mixed mode)
app2:Logs admin$ /usr/bin/java -version
java version "1.6.0_13"
Java(TM) SE Runtime Environment (build 1.6.0_13-b03-211)
Java HotSpot(TM) 64-Bit Server VM (build 11.3-b02-83, mixed mode)
How can I set it so that when appserver invokes java it is using
version 1.6?
Thanks
Frank
