This is a drop in replacement for the auth0 java-jwt library (see https://github.com/auth0/java-jwt). This jar makes sure there are no external dependencies (e.g. fasterXml, Apacha Commons) needed. This is useful when deploying to an application server (e.g. tomcat with Alfreso or Pega).

The newest version!

/**
 * Annotation used to indicate that associated property is part of
 * two-way linkage between fields; and that its role is "child" (or "back") link.
 * Value type of the property must be a bean: it can not be a Collection, Map,
 * Array or enumeration.
 * Linkage is handled such that the property
 * annotated with this annotation is not serialized; and during deserialization,
 * its value is set to instance that has the "managed" (forward) link.
 *
 * All references have logical name to allow handling multiple linkages; typical case
 * would be that where nodes have both parent/child and sibling linkages. If so,
 * pairs of references should be named differently.
 * It is an error for a class to have multiple back references with same name,
 * even if types pointed are different.
 *
 * Note: only methods and fields can be annotated with this annotation: constructor
 * arguments should NOT be annotated, as they can not be either managed or back
 * references.
