BeanUtils.isSimpleValueType() returns false for enums overriding a method [SPR-16278]

[spring-projects-issues]

Eetu Huisman opened SPR-16278 and commented

BeanUtils.isSimpleValueType() uses Class.isEnum() to determine whether a type is an enum. Class.isEnum(), however, returns false for certain enum values, namely ones overriding a method in their superclass. Using Enum.class.isAssignableFrom() instead would make the behavior more predictable.
