The following Exception occurs while executing test for Merlin new methods which are added for retrieving a particular Listener instances added to a Component.

gnumake: *** [run] Error 1

This happens on all platforms (win32 , solSparc, Linux , Solx86) on build 75 and was not occuring in any of the previous builds.

Steps to reproduce this bug :

Test files:
==========

1)Test files can be bringover or copied from AWT-SQE master work
space at:

 /net/sqesvr/export/awt/awt_ws/getFooListeners

2)Type gnumake clean at test root directory

4)Then type gnumake
  This will compile all the java files in src directory and creates required classes in Classes directory .

But from build 75 onwards this compiles java files but throws Exception before begining the Test as follows:

Cleaned file(s) in GetFooListener.

Test Suite Description :
This test suite tests "getListeners Completion" feature for AWT and Swing.
In Merlin new methods are added for retrieving a particular Listener instances added to a Component. Thus for each listener type, there is corresponding getFooListeners() method.The methods that are to be tested is added to a properties file. The methods are read from this and then tested by adding and removing the methods & calling the corresponding getFooListeners() method.

            FooListener[] listeners = <comp>.getFooListeners();
 Thus for each method Foo will be replaced by the corresponding method and will be tested
