RFR: 8375011: OldJTable.java - NullPointerException when columnData is null [v3]

[ANUPAM DEV]

> Hi,
> 
> This is a fix for NPE in OldJTable.addColumn
> 
> The addColumn method in OldJTable.java was unconditionally calling columnData.toArray(), which caused a NullPointerException when columnData was null (e.g., when called from addColumn(Object, int)).
> 
> This commit adds a null check to safe-guard against this NPE, passing null to the underlying DefaultTableModel when columnData is missing.
> 
> Kindly review.
> 
> Regards,
> Anupam
