I'm struggling with an issue(Java/Scala web project with Gradle), because I have to upgrade apache tika version to at least version 1.22, from 1.19.1(previous version have security vulnerabilities). But when i try to change version(even to lower version) i receive an exception
org.osgi.framework.BundleException: The activator org.apache.tika.config.TikaActivator for bundle org.apache.tika.core is invalid

I'm not using any configuration file, I have upgraded only the library(exception is thrown inside library, I have nothing in stacktrace reffering to my code). Version of tika dependencies are different, main concern is org.osgi:org.osgi.core upgrade from 4.0.0 to 6.0.0. I've forced in gradle to use version 4.0.0 in project, and i have received error, that org.osgi.framework.BundleActivator class is not found. The difference between classess according to documentation is additional annotation @ConsumerType. I think this is causing the problem. Is there any way to solve this?
