           Summary: error using idrefs to external types
           Product: Ant
           Version: 1.6.5
          Platform: Other
        OS/Version: other
            Status: NEW
          Severity: normal
          Priority: P2
         Component: Core
        AssignedTo: dev@ant.apache.org
        ReportedBy: cbotev@yahoo.com


Hi!

I use the cc task <http://ant-contrib.sourceforge.net/cc.html> with Ant 1.6.5. I
came accross the following problem. If I install the cpptasks.jar file in a
directory other than Ant's lib directory, I am unable to use idrefs to elements
defined in cpptask. For example, if within the cc task I use a defineset element
to set a precompiler #define, I get an error:

... doesn't denote a DefineSet.

On the other hand, if I install cpptasks.jar in the ant/lib directory,
everything works OK.

The exception is raised at DataType.java:154-156. The isAssignableFrom() call
returns false even though the required and the referenced class have the same
type signatures. What I found was that if cpptasks.jar is not in ant/lib, the
classes are loaded using different class loaders. I am not sure about the
implementation of Class.isAssignableFrom() but I suspect it considers classes
loaded with different loaders to be different classes.
