> Some analyzers in contrib provide setters for stopword / stem exclusion sets / hashtables
etc. Those setters should be deprecated as they yield unexpected behaviour. The way they work
is they set the reusable token stream instance to null in a thread local cache which only
affects the tokenstream in the current thread. Analyzers itself should be immutable except
of the threadlocal. 
> will attach a patch soon.
