And the tests verify that information. My objective was to make the AccessFlags returned for a class reflect the class file format version number of the underlying class. Currently, it is implicitly the current class file format version supported by the VM, not necessarily the version of the class loaded. Suggestions welcome for how that is exposed in the APIs and implemented. ------------- PR: https://git.openjdk.org/jdk/pull/11399
