David, Here's an altogether different approach, but if your developers' goal is to control what version of byte code is created, have them utilize the -source and -target attributes of the <javac> task. I have my developers do that and it allows me to use the latest JDK for all builds (400+ development streams) while they're able to build components and applications executing in JVMs from 1.4 --> 1.6

Actually, that's the conflict I was worried about. Jenkins allows me to specify both the Java version and the Ant version. I WANT to use the Java version specified in Hudson control panel and not whatever JAVA_HOME might be set to. I'll have to use some mechanism that uses the defaults if ${javac.executable} isn't defined and whatever ${javac.executable} is if it is defined.
