             Summary: classloaders issue loading resources when extending Tika
                 Key: TIKA-1145
                 URL: https://issues.apache.org/jira/browse/TIKA-1145
             Project: Tika
          Issue Type: Bug
          Components: config, mime
    Affects Versions: 1.3
         Environment: Tika as part of standard Solr distribution
            Reporter: Maciej Lizewski


I noticed that ServiceLoader is using different classloader when loading 'services' like Parsers, etc (java.net.FactoryURLClassLoader) than MimeTypesFactory (org.eclipse.jetty.webapp.WebAppClassLoader) when loading mime types definitions. As result - it works completely different:

When jar with custom parser and custom-mimetypes.xml is added to solr.war - both resources are located and loaded (META-INF\services\org.apache.tika.parser.Parser and org\apache\tika\mime\custom-mimetypes.xml) and everything works fine.

When jar with custom parser is in Solr core lib and configured in solrconfig.xml - only META-INF\services\org.apache.tika.parser.Parser is loaded, but custom-mimetypes.xml is ignored.
