    Description

      The stream() and entries() methods share the JarEntryIterator which was made multi-release jar aware. That change caused the methods to slow down when processing a jar file that is not multi-release. It has been suggested that we should have two JarEntryIterator implementations, one for multi-release jars and one for regular jars. This issue tracks the performance investigation and any updates that result from it.
