bash start script fails with java_cmd: readonly variable

[hackmann]

We have a PlayFramework that I'm trying to package using sbt clean universal:package-zip-tarball. This generates a tgz file. When I unpack it and run -h it says that I can pass JAVA_HOME as the command line argument

-java-home <path>         alternate JAVA_HOME

but this doesn't work:

$ /opt/IDEC-1.0-SNAPSHOT/bin/idec -java-home /usr/lib/jvm/java-7-oracle
line 201: java_cmd: readonly variable

In bash.template line 255

declare -r java_cmd=$(get_java_cmd)

and on the last line it calls run() which calls proccess_args and on line 166 java_cmdis redefined

 -java-home) require_arg path "$1" "$2" && java_cmd="$2/bin/java" && shift 2 ;;

I can see that as part of revision 69c3bd5b53b6a7a3e7ecbd4b02e5248be917d040 when the main bash script was moved from JavaAppBashScript.scala to bash.template it changed

declare java_cmd=java

to the current

declare -r java_cmd=$(get_java_cmd)

Great diagnosis! Thanks for the report. If you have time to submit a quick pr, I can patch the 0.6 series. I'm a bit swamped today with holidays in the US, but I'll get to this as soon as I can.
