Upgrade Apache Commons Collections to v3.2.2

[jart]

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!

Also, do consider using Guava in the future.

@jart thanks for the PR! This codebase is EOL'd, but the available committers are discussing the issue. Can I ask whether you identified the project based on the dependency alone, a combination of dependencies, or a demonstration exploit? I don't see any active uses of ObjectInputStream (though there is an instance in a dead method), but maybe the SOAP bindings?

I identified this project by searching for pom.xml files with the insecure version. I've submitted the same pull request to twenty-two other projects.
