Subject: [PATCH 2/2] Suppress japicmp 0.27.0 false positive on PageReader

japicmp 0.27.0 reports METHOD_ABSTRACT_ADDED_IN_IMPLEMENTED_INTERFACE for
PageReader because it now extends AutoCloseable, even though PageReader
overrides close() with a default method. Add a post-analysis script that
drops only that change type from PageReader, so other checks stay active.
