I'm not sure, I didn't change any of my config files before or after.
It seems that the way OS X has it's Java installs setup with links and
stuff, that it's a little cabberwonky when strictly compared to other
platforms. OS X updated my JDK in between compiles ( I never stopped
Tomcat), so suddenly everything I was working on stopped working. AHH! :)

You could also add a line setting JAVA_HOME in your maven startup
script, right? I believe this is what I have done,

I had this very problem this morning, and found the following shell
script on some website and ran it with:
sh ./setJDK.sh 1.4.2
~steve
#!/bin/sh
cd /System/Library/Frameworks/JavaVM.framework/Versions
CURJDK="`readlink CurrentJDK`"
echo Current JDK version: $CURJDK
if [ "$1" == "" ]; then

VERFOUND=`ls | grep $1 | head -n 1`

BASE="`basename $0`"
echo Error: Could not change JDK-- version $1 not installed!
echo Run $BASE without arguments to see a list of installed versions.

echo You must now enter your Mac OS X password to change the JDK.
sudo ln -fhsv $1 CurrentJDK

I went ahead and ran the OS X update to get Java 5 as the default. I
was worried that it would cause problems (our production servers
still run JVM 1.4.2) and it has.
I updated my build.properties with maven.compile.source=1.4 and
maven.compile.target=1.4, I set JAVA_HOME so it points to my older
Java installation, and I even replaced the sym link for /usr/bin/javac.
When I do a build on my machine it runs fine, but when I copy it up
to one of our app servers, I get a wide variety of "Unsupported
major.minor version 49.0" errors on a lot of classes, particularly
every time a tool tries to load in an iframe.
What have I overlooked? Is there a way to verify after the fact that
my object files were indeed produced by the 1.4.2 compiler?
