/**
 *  Defines a map that allows bidirectional lookup between key and values
 *  and retains both keys and values in sorted order.
 *  
 *  Implementations should allow a value to be looked up from a key and
 *  a key to be looked up from a value with equal performance.

 * @deprecated Apache Commons Collections version 3.x is being deprecated from AEMaaCS. The upgraded version 4.4 of Commons Collections is already included as replacement. Customers are advised to upgrade to this version of the library. Please note: the package name was changed to org.apache.commons.collections4. Further note that there are AEM APIs currently exposing the old collections classes; these will be updated in upcoming releases.
