> There are currently some weaknesses in the serialization and concurrency facets of the AbstractListParseFilter and AbstractParseFilter.
> Serialization adjustments
> * declare explicit serialVersionUID fields
> * make Collection-based fields transient and implement custom read/write methods
> Concurrency adjustments
> * remove the Collections.synchronizedXXX types
> * use synchronized blocks to wrap all access to the fields; this will increase the atomicity to the complete interactions with the fields, instead just each method call
> Open questions
> * since AbstractListParseFilter adds thread-safety, should the AbstractParseFilter also be thread-safe (the 'toggle' method's not safe because it's not atomic)
