• the MicroEdition-Configuration and MicroEdition-Profile attributes are missing
• changing these mobile jdk settings doesn't add them, or change them.

other issues:

• the MANIFEST.MF and the JAD are not kept in sync: i.e., the JAD file contains different values from the Manifest
• when the 'keep user-defined JAD file' option is selected, changes in the JAD file are ignored until you re-open the 'mobile module settings' dialog.

With these problems the JAR files produced are useless. They will not run on actual devices.

(note that there is no 'JavaME plugin' component - so I selected a generic one...
