By default, dubbo provides an adaptive implementation
“AdaptiveExtensionFactory”, showed below and configured in [3], adaptive class
code should not be created dynamically for ExtensionFactory.
@Adaptive
public class AdaptiveExtensionFactory implements ExtensionFactory {
private final List<ExtensionFactory> factories;
public AdaptiveExtensionFactory() {
The exception you caught was throwed here[1], which only happens when
AdaptiveExtensionFactory failed to load.
The only reason I can figure out now is the class loader[2], do you use a
customized class loader in your project?
