Imports

com.fasterxml.jackson.databind.JavaType, com.fasterxml.jackson.databind.type.TypeBindings, .TypeFactory, java.lang.reflect.Method, .ParameterizedType, .Type, .TypeVariable, .WildcardType, java.util.ArrayList, .Objects

Internal utility functionality to handle type resolution for method type variables based on the requested result type: this is needed to work around the problem of static factory methods not being able to use class type variable bindings (see [databind#2895] for more).

Since: 2.12
