Classes are listed in order of precedence, starting with the immediate super-class, followed by interfaces class directly declares to implemented, and then recursively followed by parent of super-class and so forth. Note that Object.class is not included in the list regardless of whether endBefore argument is defined or not.
    
    Parameters:
    
    endBefore - Super-type to NOT include in results, if any; when encountered, will be ignored (and no super types are checked).

public static Class<? extends Enum<?>> findEnumType(EnumMap<?,?> m)
```
    Helper method that can be used to dynamically figure out enumeration type of given EnumSet, without having access to its declaration. Code is needed to work around design flaw in JDK.
  - findEnumType
```
public static Class<? extends Enum<?>> findEnumType(Enum<?> en)
```
    Helper method that can be used to dynamically figure out formal enumeration type (class) for given enumeration. This is either class of enum instance (for "simple" enumerations), or its superclass (for enums with instance fields or methods)
  - findEnumType
```
public static Class<? extends Enum<?>> findEnumType(Class<?> cls)
```
    Helper method that can be used to dynamically figure out formal enumeration type (class) for given class of an enumeration value. This is either class of enum instance (for "simple" enumerations), or its superclass (for enums with instance fields or methods)
  - findFirstAnnotatedEnumValue
```
public static <T extends Annotation> Enum<?> findFirstAnnotatedEnumValue(Class<Enum<?>> enumClass,
                                                                         Class<T> annotationClass)
```
    A method that will look for the first Enum value annotated with the given Annotation.
    If there's more than one value annotated, the first one found will be returned. Which one exactly is used is undetermined.
    
    Parameters:
    
    enumClass - The Enum class to scan for a value with the given annotation
    
    annotationClass - The annotation to look for.
    
    Returns:
    
    the Enum value annotated with the given Annotation or null if none is found.
    
    Throws:
    
    IllegalArgumentException - if there's a reflection issue accessing the Enum

  - isJacksonStdImpl
```
public static boolean isJacksonStdImpl(Object impl)
```
    Method that can be called to determine if given Object is the default implementation Jackson uses; as opposed to a custom serializer installed by a module or calling application. Determination is done using JacksonStdImpl annotation on handler (serializer, deserializer etc) class.
    NOTE: passing `null` is legal, and will result in true being returned.
  - isJacksonStdImpl
```
public static boolean isJacksonStdImpl(Class<?> implClass)
```
  - isJDKClass
```
public static boolean isJDKClass(Class<?> rawType)
```
    Some aspects of handling need to be changed for JDK types (and possibly some extensions under javax.?): for example, forcing of access will not work well for future JDKs (12 and later).
