java - Why does bnd figures my bundle REQUIRES optional services (*, 0..n, ReferenceCardinality.MULTIPLE)? -

my bundle defines interface, , component uses interface implementations call them (if exists...).

a analogy logservice; if 1 (or more) exists, calls them message.

here's ds declaration:

@reference(cardinality= referencecardinality.multiple,         policy = referencepolicy.dynamic,         service = itestresultsparserservice.class) public void bindtestresultsparser(itestresultsparserservice parser) {     testresultsparserservices.add(parser); } public void unbindtestresultsparser(itestresultsparserservice parser) {     testresultsparserservices.remove(parser); } 

so expect bundle able deploy or without services implementations.

however, here's eclipses gives me:

why? isn't requirement @ all! it's optional.

i found this ticket seems talk issue, not clear why it's been closed. added bnd.bnd, stated in ticket:

-resolve.effective: active;skip:="osgi.service"

since bug has been fixed, , not question possible answer, i'm closing it.
