-------------------------------
Would update to Commons Collections 3.2.2 alleviate the remote code execution
vulnerability ?
See https://issues.apache.org/jira/browse/COLLECTIONS-580

> TL;DR: If you have commons-collections on your classpath and accept and
> process Java object serialization data, then you may have an exploitable
> remote command execution vulnerability.
> Brief search in code base for ObjectInputStream reveals several places where
> the vulnerability exists.
