a problem with Changeset [18567]: using ANT_OPTS as jvm arguments for scalacfork

Hi!

Where is my mistake? After Changeset [18567] I have:

$ ant -version
Apache Ant version 1.7.1 compiled on June 24 2009
$ echo $ANT_HOME
/usr/share/ant
$ echo $ANT_OPTS
-Xms1024M -Xmx2048M -Xss2M -XX:MaxPermSize=256M
$ ant dist
Buildfile: build.xml
