Only on Win98 by Fcs_P:

In closing window HotSpot Virtual Machine Error occurs, and the cases seems to
be specified.

When getContentPane().setLayout() is used and the following are set as
an argument of setLayout() in the application;

FlowLayout()
GridLayout()
BorderLayout()


But it is intermitted.
This phenomenon is seen also on Fcs_O.

The error message is;

# HotSpot Virtual Machine Error, EXCEPTION_ACCESS_VIOLATION
#
# Error ID: 4F533F57494E13120E43505002BE
#

abnormal program termination


With Classic VM, an error dialog appears and abnormal termination occurs.
The detail of the error is;

To reproduce,

3. Close the window from the system menu.

Then, the error occurs, though it is intermitted.
