Segmentation fault when mousing over JTable that overrides getToolTip()

I'm running NetBeans 6.5 RC1 on Ubuntu Linux.
http://www.netbeans.org/servlets/NewsItemView?newsItemID=1298

System information:
Java: 1.6.0_10-rc2; Java HotSpot(TM) Client VM 11.0-b15
System: Linux version 2.6.24-21-generic running on i386; UTF-8; en_US (nb)


There is a dialog box, SQL History that has a JTable where the JTable constructor overrides getToolTip()

       new JTable() {

            public String getToolTipText(MouseEvent e) {
                java.awt.Point p = e.getPoint();
                int rowIndex = rowAtPoint(p);
                int colIndex = columnAtPoint(p);
                return view.getSQLHistoryTooltipValue(rowIndex, colIndex);
            }
        };


After awhile of mousing over the cells of the JTable, NetBeans crashes.

All the information I see so far is:

/home/jbaker/builds/r2/main/nbbuild/netbeans/bin/../platform9/lib/nbexec: line 493: 11335 Segmentation fault


If I use JDK 1.5.0_16 with the same version of NetBeans, no segmentation fault occurs.
To reproduce (should be an easier way)

1) On Ubuntu running JDK 1.6.0_10, install NetBeans 6.5 RC
http://download.netbeans.org/netbeans/6.5/rc/

2) In the Services tab, connect to sample connections under Databases

3) Expand a connection, select a table, right-click and choose View Data
Repeat for other tables a few times

4) Right-click in the editor and choose SQL History

5) Mouse over the table listing SQL statements, move the mouse across the
statements a few times without clicking

Result: NetBeans crashes with segmentation fault

I don't see a hs log file

Is there a way to force a log file to be generated ?
