Sonar scanner throws null pointer exception while running the scanner. The error points out to the an enum. which implements a typical interface.
I remember running the scanner few months ago without any issues but this times it's different, any help is appreciated.
public enum ItsAnEnum implements SomeField<SomeEnumModuleType> {
public interface SomeField<T extends CodeEnum> extends NumericEnumWithLabel, CodeEnumWithLabel {
