'Coz of this error test cases are failing while running the various drag & drop test suite which supposed to be run to complete the merlin B-42 quicklook testing.
A tar file is attached which contains three java files. Simply compile & run the TestDND file & if the error mentioned above appears on the console than the bug is reproduced.
