Yes.  I have to use J2SE v5.0 as I have to use generic types.  I guess
Groovy does support this yet though.  However the Groovy script I am
trying to put together (to replace a Python script) doesn't need to know
about generics. 

I am using Debian GNU/Linux Sarge with kernel 2.6.9 with Sun's JDK 1.5
installed by creating a deb file and installing that.  As far as I am
aware there are no problems with the JDK installation.

I have found that whilst the script:

        #! /usr/bin/env groovy
        
        "ant".execute()

works fine, the script:

        #! /usr/bin/env groovy
        
        //expectedPrompts = [
        //                   "Enter length of first side: ",
        //                   "Enter length of second side: ",
        //                   "Enter length of third side: "
        //                   ]
        
        //outputIntroducers = [
        //                     "Perimeter is: ",
        //                     "Area is: "
        //                     ]
        
        //testTuples = [
        //              ["0.0", "0.0", "0.0", "0.0", "0.0"],
        //              ["0.0", "1.0", "1.0", "2.0", "0.0"],
        //              ["1.0", "1.0", "2.0", "4.0", "0.0"],
        //              ["1.0", "1.0", "1.0", "3.0", "0.433012"],
        //              ["3.0", "4.0", "5.0", "12.0", "6.0"],
        //              ["-1.0", "-1.0", "-1.0", "-", "-"],
        //              ["1.0", "1.0", "3.0", "-", "-"],
        //              ["1.0E1000", "1.0E1000", "1.0E1000", "Infinity", "NaN"]
        //              ]
        
        // expectedPrompts.each { println it }
        
        antProcess = "ant".execute()
        
        // antProcess.in.eachLine { println it }

produces the output:

I guess this must be a bug in Groovy so I guess I should enter a bug
report.  Unless of course I am doing something silly which is entirely
possible given that I am a beginner.
