Maciej Lizewski commented on TIKA-1145:
---------------------------------------
I would rather suggest opposite - ServiceLoader is properly using the
classloader provided in TikaConfig (ServiceLoader is instantiated in
TikaConfig::init() and classloader configured in TikaConfig is passed to
ServiceLoader and stored in loader attribute). This part works as expected -
uses provided classLoader.
Problem is with MimeTypesFactory which ignores classLoader from TikaConfig and
always is using:
ClassLoader cl = MimeTypesReader.class.getClassLoader();
which is wrong in case user provided custom classLoader.

> 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.
