[PATCH] Robustness of checkTaskClass against linkage errors

           Summary: [PATCH] Robustness of checkTaskClass against linkage
                    errors
           Product: Ant
           Version: 1.6.0
          Platform: PC
        OS/Version: Linux
            Status: NEW
          Severity: Minor
          Priority: Other
         Component: Core
        AssignedTo: dev@ant.apache.org
        ReportedBy: jglick@netbeans.org


I can't remember now exactly how it came up, but I tried to run a script with
some task that could be loaded but not fully linked (some missing dependency,
etc.), and Ant behaved in a way that was difficult to debug - throwing an error
from checkTaskClass without giving a clue as to which task was in error. The
attached patch just checks for this condition, including enough information to
help you resolve the problem, before rethrowing the error as a BuildException.

(BTW: I am copying the call to Project.log(..., MSG_ERR) before throwing the
exception, for consistency w/ the catch of NoSuchMethodException, though I don't
really follow what the purpose is of logging an error message you are about to
throw as a BuildException.)
