Ant task inheritRefs attribute is not working as expected

[Mohit Jagetia]

Hi,
I have a problem in downcasting the attached reference to a project (when i call the target from another build file).



- The downcasting works fine in the same ant build file.
- Also it works for simple types eg. string, int etc. but not for complex type eg. class having mixed datatype int, string or other classes



Senario:
I have a main build.xml calling target "Target2" of build2.xml using task "Ant"
All the references and properties are expected to be transfer to Target2 and should be retrieved / casted to the original types.



Details:
For the above senario i created a custom task "mainTask" which create an instance of Subq object and uses addReference() method of Project class to attach the reference of it

x = new Subq();
x.setA(33, 55);
prj.addReference("myobj1", x);

This attached reference is expected to pass to the Target2 of build2.xml file with following ant task

<mainTask />
<ant antfile="build2.xml" dir="." output="stdout.log" inheritall="true" inheritrefs="true" >
			<target name="Target2" />
</ant>

In the Target2 of build2.xml i have another custom task which prints all the references received and try to retrive the attached reference "myobj1"

System.out.println(prj.getReferences().toString());
Object mysubq = prj.getReference("myobj1");
Class cls = mysubq.getClass();
System.out.println("The inner type of the object is: " + cls.getName());
if (mysubq instanceof Subq) {
System.out.println("mysubq is an instance of Subq class!");
}else{
System.out.println("mysubq is NOT an instance of Subq class!");
}
Subq mysubq2 = (Subq) mysubq;

I can see the reference "myobj1" in hashtable with hastable.toString() method

   [main2T] --------- ref check ----------
Class java.util.Hashtable loaded from parent loader (parentFirst)
   [main2T] {ant.executor=org.eclipse.ant.internal.ui.antsupport.EclipseSingleCheckExecutor@1df8b99, myobj3=com.t1.Subq@1462851, ant.targets=[, Target2], TestDummy1=com.t1.Test1Dummy@698403, myobj2=com.t1.Subq@1010058, ErrorLogging=org.apache.tools.ant.Project@bdab91, myobj1=com.t1.Subq@4ac00c, ant.PropertyHelper=org.apache.tools.ant.PropertyHelper@1865b28, MJString1=MJString1, ant.parsing.context=org.apache.tools.ant.helper.AntXMLContext@1cac6db, ant.ComponentHelper=org.apache.tools.ant.ComponentHelper@1c56c60, ant.projectHelper=org.apache.tools.ant.helper.ProjectHelper2@4e280c, eclipse.ant.targetVector=[Target2]}
   [main2T] --------- ref check ----------

I check the type of the object

   [main2T] The inner type of the object is: com.t1.Subq

But when i try to cast it with Subq it throws ClassCastException
