Copying and Pasting from one table cell into another causes JVM to throw exceptions
and JTable application to crash.
The following is the exception thrown when I tried to copy and paste from one
cell into another in the JTable testcase:
==================
Exception occurred during event dispatching:

==================

To reproduce this behavior:

1- Compile and run the (following) jTable.java test case under any platform
2- Use the mouse to select some text fro a JTable cell
3- Do "Ctrl+C" on the selected text to copy it
4- Choose another cell
5- Do "Ctrl+V" to paste the text
6- Note that the above exception is thrown
