Description

Groovy does not detect Oracle's Java 7 - instead, it will use only the Apple JDK6, unless JAVA_HOME is set.

I'll try to get around to doing a git pull, but for now, the solution is to change startGroovy

# Attempt to set JAVA_HOME if it's not already set.
if [ -z "$JAVA_HOME" ] ; then
    if $darwin ; then
        jdkhome="`java -XshowSettings:properties 2>&1 | grep java\\.home | awk '{print $3}' | rev | cut -d '/' -f 2- | rev`"
        [ -d $jdkhome ] && export JAVA_HOME=$jdkhome
        [ -z "$JAVA_HOME" -a -d "/Library/Java/Home" ] && export JAVA_HOME="/Library/Java/Home"
        [ -z "$JAVA_HOME" -a -d "/System/Library/Frameworks/JavaVM.framework/Home" ] && export JAVA_HOME="/System/Library/Frameworks/JavaVM.framework/Home"
    else

I've tested this with both the Apple and Oracle JDKs as the default, and it works correctly. My shell-fu is not strong however, and there's certainly a better way to do this.
