    Description

      With Groovy 1.5.1, I used the <groovyc> Ant task with a nested <javac> which has the 'source' and 'target' attributes specified using Ant properties:

      <groovyc ...
      <javac debug="${javac.debug}" source="${javac.compatibility.source.version}" target="${javac.compatibility.target.version}"/>
      </groovyc>

      The 'javac.compatibility.source.version' and 'javac.compatibility.target.version' properties are both set to '1.4'. This worked fine in 1.5.1, but upgrading to Groovy 1.6.0 I get the following error:

      [groovyc] org.codehaus.groovy.control.MultipleCompilationErrorsException: startup failed, Invalid commandline usage for javac.
      [groovyc] javac: invalid source release: ${javac.compatibility.source.version}

      The properties are set up correctly (<echoproperties/> proves it), but for some reason they're not getting resolved in this particular context. If I convert the Ant script to use AntBuilder within a <groovy> script element, it resolves the problem, e.g.

      <groovy>
      ant.groovyc( ... ) {
      ...
      javac( debug:properties["javac.debug"], source:properties["javac.compatibility.source.version"], target:properties["javac.compatibility.target.version"] )
      }
      </groovy>
