I've successfully fixed the issue using JDK SPI — it now works perfectly.
Here’s the working pseudo-code:
```
// auron-core
public interface AuronAdaptorProvider {
AuronAdaptor create();
}
public abstract class AuronAdaptor {
public static AuronAdaptor getInstance() {
if (INSTANCE == null) {
synchronized (AuronAdaptor.class) {
if (INSTANCE == null) {
ServiceLoader<AuronAdaptorProvider> loader =
ServiceLoader.load(AuronAdaptorProvider.class);
for (AuronAdaptorProvider p : loader) {
INSTANCE = p.create();
break;
}
if (INSTANCE == null) {
throw new IllegalStateException("No
AuronAdaptorProvider found");
}
}
}
}
}
}
return INSTANCE;
}
// spark-extension
public class SparkAuronAdaptorProvider implements AuronAdaptorProvider {
@Override
public AuronAdaptor create() {
return new SparkAuronAdaptor();
}
}
```
