- WARNING: Unlikely argument type for collection methods using 'Object' - INFO: Unlikely argument type for method equals
As analyzed in https://bugs.eclipse.org/bugs/show_bug.cgi?id=410218#c49(only Group A and Group C are reported now), most of these are bugs, that
should be fixed. The remaining ones can be rewritten (e.g. by instanceof checks and casts)
or suppressed with @SuppressWarnings("unlikely-arg-type").
