providing new interfaces, implementations and utilities.

It was found that the Apache commons-collections library permitted code
execution when deserializing objects involving a specially constructed
chain of classes. A remote attacker could use this flaw to execute
arbitrary code with the permissions of the application using the
commons-collections library. (CVE-2015-7501)
