    Attachment: LUCENE-3731_speed.patch

Hi Tommaso, I noticed some of the tests here are really slow... digging in I think we have
some perf issues:

   [junit] Testsuite: org.apache.lucene.analysis.uima.UIMABaseAnalyzerTest
   [junit] Tests run: 3, Failures: 0, Errors: 0, Time elapsed: 52.302 sec

   [junit] Testsuite: org.apache.lucene.analysis.uima.UIMATypeAwareAnalyzerTest

See the patch below (which cannot be committed yet)... currently i had to add sync around
the analysis engine, but it avoids recreating the CAS for each document... which seems to
cause the perf problems

> As discussed in SOLR-3013 the UIMA Tokenizers/Analyzer should be refactored out in a
separate module (modules/analysis/uima) as they can be used in plain Lucene. Then the solr/contrib/uima
will contain only the related factories.
