Mojo thread safety assertion checklist

Sometimes it can be hard to determine if a plugin and the underlying libraries are thread-safe, so when adding @threadSafe the following checklist can be used:

Check all static fields/variables in plugin/plugin code are not subject to threading problems.
Check any plexus components.xml; if the components defined are singletons they need to be threadsafe.
Check for presence of known tainted libraries.

This checklist qualifies for a "simple thread safety" review of a mojo.

Known non-thread safe libraries

Known thread safety problems have been fixed in the following library versions:

plexus-utils 2.0.5
maven-archiver 2.4.1
plexus-archiver 1.0
plexus-io 1.0
