Upgrade Apache Commons Collections to v3.2.2

[ghost]

Version 3.2.1 has a CVSS 10.0 vulnerability. That's the worst kind of vulnerability that exists. By merely existing on the classpath, this library causes the Java serialization parser for the entire JVM process to go from being a state machine to a turing machine. A turing machine with an exec() function!
