For both sun javac and jikes you can use the target flag to set this ie for 
1.1 compatibility
         javac -target 1.1 File.java
         jikes -target 1.1 File.java

To get antlr to build under 2.7.2 i always had to run through this procedure:

         cd antlr-2.7.2
         find antlr -name '*.class' -exec rm {} \;
         javac -classpath . antlr/build/*.java
         javac -classpath . antlr/J*.java
         java -classpath . antlr.build.Tool build
         java -classpath . antlr.build.Tool jar

There are also interesting bootstrapping problems you end up with a 
different result i think depending on what antlr.jar is sitting in the 
build directory when you start.
