           Summary: Compiler dies with [javac] javac: invalid flag: -source
                    1.4
           Product: Ant
           Version: 1.6.2
          Platform: PC
        OS/Version: Linux
            Status: NEW
          Severity: normal
          Priority: P2
         Component: Core tasks
        AssignedTo: dev@ant.apache.org
        ReportedBy: ant@sourceillustrated.com


I'm using jdk 1.5 but need to compile my classes with the -source 1.4 option to
javac.

I have my target configured as:
-----------------------------------------------------
 <javac destdir="${product.classes}" nowarn="on" debug="${java.debug}">
            <compilerarg value="-source 1.4"/>
            <classpath>
                <fileset dir="../lib">
                    <patternset refid="compile.libs"/>
                </fileset>
            </classpath>
            <src path="src"/>
 </javac>
-----------------------------------------------------
Running ant gives me the following output:
-----------------------------------------------------
build.product:
