> When setting (changing) values for features, sometimes index corruption
> checking needs to be done, and sometimes changes need to be journaled. Both
> of these need to identify the feature involved. This operation should be
> fast and memory-cache-friendly (e.g. not involve following a long chain of
> dereferencings).
> Add static final fields that represent features used by a particular JCas
> class, which have names derived from the short-feature-name, and won't
> collide with other names, and set these using the same JCasRegistry mechanism
> to unique values within a class loader. This allows the same JCas cover
> classes to be used with different type systems.
> Change the corruption testing logic to use BitSets and have a version which
> uses these indexes as well as one which uses the FeatureImpl featureCode.
> Keep one extra table mapping these codes to FeatureImpls, per type system.
