andConstructor.newInstance(Object...)
and their reflection implementation classes.The
SHOW_HIDDEN_FRAMES
option can also be used to show all reflection frames and it will also show other hidden frames that are implementation-specific.- API Note:

orConstructor.newInstance
such asClass.newInstance
are not filtered or controlled by any stack walking option.
