Contrib Analyzer Setters should be deprecated and replace with ctor arguments
-----------------------------------------------------------------------------

                 Key: LUCENE-2051
                 URL: https://issues.apache.org/jira/browse/LUCENE-2051
             Project: Lucene - Java
          Issue Type: Improvement
          Components: contrib/analyzers
    Affects Versions: 2.9.1
            Reporter: Simon Willnauer
            Priority: Minor
             Fix For: 3.0


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.
