The "indexMetaInf" was introduced in the Ant 1.8.0
Add "indexMetaInf" attribute into jar task when J2SEProject will require Ant 1.8.
Fixed jet-main 8bd331b0724f
Integrated into 'main-golden', will be available in build *201010260000* on http://bits.netbeans.org/dev/nightly/ (upload may still be in progress)
