description

try to resolve bundle req

  • bundle req has the requirement namespace="ns",name="name"

so we look for the same capability namespace="ns",name="name"

  • bundle cap has the capability namespace="ns",name="name"
  • but bundle cap has also a Requirement osgi.service;filter:="(objectClass=java.lang.Readable)";effective:=active;cardinality:=multiple.
  • this could be providet by itsselve osgi.service;objectClass:List<String>="java.lang.Readable" (target property of @Reference is not processed)

Issues:

  • it resolves bundle capfora which provides a capability that is required by bundle a -> provides also the capability that is required from bundle cap ( osgi.service;objectClass:List<String>="java.lang.Readable").
  • But in this case bundle a is not in the resolveresult
  • bundle b is also resolved. (not needet, cap has the needet capability by its own)
