When you specify package groupings inside ImportOrder, that same ordering is applied to the single group of static imports. Eclipse's Organize Imports feature, however, sorts all static imports alphabetically within a single group--ignoring the package grouping order. There's no way to synchronize the behavior between the two tools.
For example, using "org,java" produces this in Eclipse:
import static java.Math.abs; import static org.foo.Bar.*; import org.foo.Foo; import java.util.Set;
For maximum flexibility, add an option to control whether or not the static imports (when grouped using "top" and "bottom" option) are sorted normally or according to the package groupings.
