src/hotspot/share/classfile/systemDictionaryShared.cpp line 672:

> 670:     SystemDictionaryShared::check_for_exclusion(k, &info);
> 671:   };
> 672:   _dumptime_table->iterate_all(check_for_exclusion);

Can't this be changed to just:
`_dumptime_table->iterate_all(SystemDictionaryShared::check_for_exclusion);`

or maybe even:
`_dumptime_table->iterate_all(check_for_exclusion);`
