Setting "anchor" field in GridBagConstraints as GridBagConstraints.ABOVE_BASELINE for all components when the row does not have any Baseline set. A NullPointerException is thrown. this Exception is thrown or all the components that has been added into the layout with the same "anchor" type.

The Javadoc points out that if the row does not have a baseline set then the components will be centered vertically (This is mentioned in the anchor Description)

This is consistently happening in the solaris platform - need to test in other platforms

Attached Two Sample codes to reproduce the bugs. (Written for 2 anchor types GridBagConstraints.ABOVE_BASELINE and GridBagConstraints.BELOW_BASELINE
