  Subject: Using if/unless within a target

  I am trying to use "if" within a target tag, and the documentation indicates that if the
property is set, the target will be executed.  The small buildfile below indicates that this
is not the case.  When I execute this buildfile, I would expect to see: "executing test1",
instead I don't see any echo messages.  Likewise, if I replace the "if" with "unless", I see
both echo messages.  

  Have I set this up incorrectly?  When I turn on verbose, I see the message that "string.present"
is set to true. 
  This behavior seems buggy and contrary to the documentation. 

  I am using the release version 1.1, and have also tried it with last night's build (08/09)
with the same result.

    <target name="check_for_depend" > 
      <available property="string.present" classname="java.lang.String" /> 
      <available property="not.present" classname="foo" />              

    <target name="test1" depends="check_for_depend" if="${string.present}"> 
      <echo message="executing test1"/>        

    <target name="test2" depends="check_for_depend" if="${not.present}"> 
      <echo message="executing test2"/>        
    <target name="all" depends="test1,test2" />
