invoking groovy with -D seems to mess up main's args in some cases

Put this code in A.groovy

class A
{
    public static void main(String[] args) {
	args.each { println it }
    }
}

Run

groovy -Da=b A.groovy -no-file

Actual output:

-n
o-file

Expected output:

-no-file

Omitting the -Da=b causes the arguments to be processed correctly. It appears that groovy's startup script is calling java correctly. In other words, running this command:

/opt/jdk/bin/java -classpath /opt/groovy/lib/groovy-1.8.2.jar -Dscript.name=/opt/groovy/bin/groovy -Dprogram.name=groovy -Dgroovy.starter.conf=/opt/groovy/conf/groovy-starter.conf -Dgroovy.home=/opt/groovy -Dtools.jar=/opt/jdk/lib/tools.jar org.codehaus.groovy.tools.GroovyStarter --main groovy.ui.GroovyMain --conf /opt/groovy/conf/groovy-starter.conf --classpath . -Da=b A.groovy -no-file

results in the same output.
