      This is forked from JDK-8342642 and filed as a general issue for archived boxed Integer cache when it's recreated at runtime. In short, current code drops the entire primitive cache when the CDS archived version of the cache is too short. This poses a problem with code that uses CDS archived cache instances, since the boxed equality would break when comparing the CDS-archived value and the Integer cached value recreated at runtime.

      https://github.com/openjdk/jdk/pull/21672#issuecomment-2434359711 discusses a possible fix for the Integer cache. JDK-8342642 has additional details.
