Unable to use AutoDelegate to delegate FileSystemProvider

[stevenschlansker]

I am trying to make a delegate of java.nio.file.spi.FileSystemProvider.

I write out:

@AutoDelegate(FileSystemProvider.class)
public class MyFileSystemProvider extends AutoDelegate_MyFileSystemProvider {
    public MyFileSystemProvider() {
        super(null); // TODO
    }
}

but unfortunately this fails:

java.lang.IllegalStateException: A mismatch between the number of interfaces found on the declaring class that correspond to the delegation targets specified via the AutoDelegate annotation. Are you sure your type implements all of the delegation targets?
    at com.ryandens.delegation.AutoDelegateProcessor.process (AutoDelegateProcessor.java:111)

Normally I would implements the service type directly, but in this case the service type is an abstract class, not an interface.

Hi @stevenschlansker - this project is currently only scoped to auto-delegation to interfaces, not to abstract classes. This is a valid use case for this project, but I don't anticipate adding support for it myself anytime soon.
