> It appears the ant script in 1.5.1 has bug in it that directly effects  
> OS X.  If you have DP10 installed but the command line set to use  
> 1.3.1 by setting PATH and JAVA_HOME, you will see the problem.  You  
> must also tell ant to use jikes with a -Dbuild.compiler=jikes.  The  
> ant script detects that it is running on OS X then picks up all of the  
> jars in  
> /System/Library/Frameworks/JavaVM.framework/Versions/CurrentJDK/ 
> Classes which are 1.4.1 classes.
>
> You may not notice this immediately because 1.3.1 classes are before  
> 1.4.1 classes.  You can verify this by calling ant with a -verbose  
> option and looking at the classpath in a javac task.
