      Description

      Example of failure in a modular environment:
      Error:java: the unnamed module reads package org.apache.ignite.internal.processors.cache.persistence.file from both ignite.core and ignite.direct.io

      This type of failure is named package inference, but it is strictly prohibited http://openjdk.java.net/projects/jigsaw/spec/reqs/#non-interference

      Ignite compatibility with Jigsaw is tested in a separate project. See details in
      https://github.com/apache/ignite/tree/ignite-11461-java11/modules/dev-utils/ignite-modules-test#ignite-modular-environment-test-project
