Niko Wittenbeck Thank you for bringing this to our attention. I will see if I can add a TikaParserProvider as mentioned in the PR. This will probably make it to version 5.10. If you cannot wait, or cannot use 5.10 because of your environment (5.10 will require Hibernate ORM 5.3), then the following should be of interest to you.

There is a workaround, I think, which is to set the "tika.config" JVM property, or the "TIKA_CONFIG" environment variable, to the path of your config file. You can use a path on the filesystem, a URL or a path on the classpath. This file will then be used by default. Of course this configuration will be used for all of your Tika bridges, which may not be what you want. But it can be useful.
See org.apache.tika.config.TikaConfig#TikaConfig() for more information (checked on Tika 1.4).
