Hi,
Should SPI-fly also work when a bundle uses the
ServiceLoader.load(class, class.getClassLoader) function?
Specifically I'm trying to convert org.openrdf to an osgi bundle.
A bundle org.openrdf.query.parser looks for implementations of
org.openrdf.query.parser.QueryParserFactory. I've added the
Require-Capability and osgi.serviceloader... and osgi.extender... to the
Manifest. This class is actually an extention of the abstract class
ServiceRegistry from another package so I also added the
Require-Capability to this bundles Manifest.
The abstract class is available via this url
https://bitbucket.org/openrdf/sesame/src/c2c4cfa901461812e15b697994a439efbadaa9e0/core/util/src/main/java/info/aduna/lang/service/ServiceRegistry.java?at=2.7.x
At line 46 in this file You'll find:
java.util.ServiceLoader.load(serviceClass, serviceClass.getClassLoader());
The bundle that exports the service is org.openrdf.query.parser.sparql.
Here I've added the Require-Capability and Provide Capability clauses.
When I run the application and enter "inspect capability service 34" I
can see the serviceloader.mediator property.
However it seems like the consumer can't find the service. Therefore I
thought the ServiceLoader.load(class, class.getClassLoader) is causing a
problem since the abstract class and implementing class are in a
different bundle.
Kind regards
