Editable JComboBox Popup is 1 to 2 pixel wider than JComboBox textfield. This can be observed only in pit build. It looks fine 6u5_b03 promoted build. Hence its a regression . I have attached screen shot of the same. The bug is reproduced in all platform.

Step to reproduced.
------------------
1) Run the testcase.
2) Click on the arrow button of the editable comboBox & observe that popup is wider than the textfield. If you see the same then the bug is reproduced.
