Guillaume Nodet updated FELIX-1131: ----------------------------------- Attachment: FELIX-1131.txt Attached is a better diff which, in addition to checking imported packages, also checks exported packages and early succeed / fail when one bundle is importing and the other one exporting the same package. > ServiceReference.isAssignableTo fails when using a factory that can not see > the exported class and the bundle exporting the service does not have a > direct wire to this class > ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------- > > Key: FELIX-1131 > URL: https://issues.apache.org/jira/browse/FELIX-1131 > Project: Felix > Issue Type: Bug > Components: Framework > Affects Versions: framework-1.6.0 > Reporter: Guillaume Nodet > Assignee: Richard S. Hall > Attachments: FELIX-1131.txt > > > * bundle A defines an interface R and a class S in different packages, whith > S implementing R > * bundle B defines a class T extending S, it has an import statement on S > package, but not on R package > * bundle C defines a ServiceFactory that export T service without any import > on any package from R, S, T > in this case, the line 426 of ServiceRegistrationImpl is executed: > allow = > getServiceRegistration().isClassAccessible(requestClass); > which looks like: > protected boolean isClassAccessible(Class clazz) > { > try > { > // Try to load from the service object or service factory class. > Class sourceClass = (m_factory != null) > ? m_factory.getClass() : m_svcObj.getClass(); > Class targetClass = Util.loadClassUsingClass(sourceClass, > clazz.getName()); > return (targetClass == clazz); > } > catch (Exception ex) > { > // Ignore this and return false. > } > return false; > } > So felix checks if the classloader used to load the factory can also load the > interface, which is not the case in my example. > So isClassAccessible returns false and the event is not dispatched to the > service listener. -- This message is automatically generated by JIRA.
