Menu Item Corrections for Right-to-Left Languages
Several bugs in the non-default alignment and text orientation for the menu items in Swing have been fixed, as this is particularly important for right-to-left languages such as Arabic.
Another issue corrected is the position of the icon and the text. For the non-default positions the text used to overlap the icon in a menu item, this is no longer the case.
All platform Look and Feel configurations will now handle menu items in right-to-left language situations. These fixes have been tested through their inclusion in the JDK 7 development release, but this is the first time they have been available via JDK 6.
Additional Languages Support in Linux Systems
Added support for SuSE Linux Enterprise Server 10 and 11 on Chinese (Simplified), Chinese (Traditional), Japanese, and Korean locales.
