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

[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
