> The current implementation of JCas classes requires that a type system 
> associated with a JCas class be committed before the JCas class is loaded.  
> This causes some existing code to fail, because they're causing a JCas class 
> to be loaded before the type system is committed (see UIMA-5554).  
> The reason for this design in v3 was to enable the computation of the offsets 
> for accessing features in feature structures to be done once and saved in 
> static final int values, for efficiency. 
> Find a new approach, which is as efficient, but is more lazy - allowing JCas 
> classes to be loaded, and later a corresponding type system commit to be run.
