Using SnowballPorterFilterFactory throws NoClassDefFoundError
-------------------------------------------------------------

                 Key: HSEARCH-232
                 URL: http://opensource.atlassian.com/projects/hibernate/browse/HSEARCH-232
             Project: Hibernate Search
          Issue Type: Bug
            Reporter: Hardy Ferentschik
            Assignee: Hardy Ferentschik
             Fix For: 3.1.0.Beta2


Trying to use SnowballPorterFilterFactory in  @AnalyzerDef will currently throw the following exception:

java.lang.NoClassDefFoundError: org/apache/solr/request/QueryResponseWriter
	at org.apache.solr.analysis.SnowballPorterFilterFactory.init(SnowballPorterFilterFactory.java:42)

The problem is SnowballPorterFilterFactory contains a log statement using SolrCore.log.fine(). SolrCore itself has then a whole list of other import statements including QueryResponseWriter. Within Hibernate Search we use a custom/shrinked version of the solr jar which only contains the classes needed for analysis. QueryResponseWriter should of course not be required (see http://repository.jboss.org/maven2/org/hibernate/apache/lucene/solr/apache-solr-analyzer/1.2.0/solrshrinker-build.xml).

The problem does not occur when the full solr jar is used.

We need to start a discussion with the solr developers regrading this logging issue.

Example annotation causing the error:
@AnalyzerDef(name="customanalyzer",
		tokenizer = @TokenizerDef(factory = StandardTokenizerFactory.class),
		filters = {
				@TokenFilterDef(factory = LowerCaseFilterFactory.class),
				@TokenFilterDef(factory = SnowballPorterFilterFactory.class,params = {
					@Parameter(name="language", value= "English")
				}),
})
