 * Whether a member supports null values injected.
 * 
 * 
Support for {@code Nullable} annotations in Guice is loose.
 * Any annotation type whose simplename is "Nullable" is sufficient to indicate
 * support for null values injected.
 * 

 * This allows support for JSR-305's
 * 
 * javax.annotation.meta.Nullable annotation and IntelliJ IDEA's
 * 
 * org.jetbrains.annotations.Nullable.
