Drag and drop operation from JList to JTextField raising exceptions.

In solaris, it is not at all copying the text of selected item of JList.

In windows, it is copying but still throwing exceptions. But it is copying only after requesting focus for the JTextField before doing drag and drop operation.

Find attached test case with the bug report.

To Reproduce the bug :

1) Compile and run the attached Java File.
2) Select any item in the JList. Drag it to JTextField beside it. You'll be getting exceptions on console. No text copied into the textfield.
3) Rerun it again, first select the JTextField, then do step 2. It copies the text into the textfield, but still raises exception.
