Hmm...  It doesn't seem right.

% cat /usr/local/bin/ecj.sh
#!/bin/sh

/usr/local/openjdk6/bin/javac -classpath /usr/local/share/java/classes/ecj.jar $1
% /usr/local/bin/ecj.sh -version
javac 1.6.0_30
% /usr/local/openjdk6/bin/javac -version
javac 1.6.0_30

Please note it isn't coming from ecj.jar.

Also, `$1' should be `$*'.

Thanks for working on this, BTW.
