a 26073:cb448d8f764a commit changed behaviour declared in javadoc and a Metaspace wrapper is no longer supported as base parameter. Respective test case should be removed from test.
Also, there is another problem with test. It uses Unsafe::getKlassPointer to receive Klass*. An uncompressed pointer is returned and then it's provided to getResolvedJavaType method for both cases: compressed and uncompressed mode. This leads to crash in case compressed mode is enabled(since, uncompressed pointer is provided and treated in getResolvedJavaType method as compressed).
