GTK:Toolbar separator overlaps on component in JToolBar for some of the cases.

Bug Info:
=========
If you set the JCheckBox or JTextField component followed by toolbar separator in JToolBar then the separator overlaps on the component which is followed by it.This issue is clearly visible on GTK Look And Feel with 2.0 version.But its not visible above GTK2.0 version and also its fine with windows look and feel.

In metal look and feel separator is not visible but it provides some space between the components which are adjacent to separator.

If you change the toolbar to vertical orientation then still we can see the separator overlap on JTextField component.



Please find the attached image for seeing the issue.
