would not be required anymore. And we would not need the wrapper to the callback routine fill_cframe_list() -- as in, we would need only one routine with the appropriate arguments passed. This got missed while fixing JDK-8164383 : jhsdb dumps core on Solaris 12 when loading dumped core. Pre-8164383, fill_cframe_list() or wrapper_fill_cframe_list() would get called, depending on whether SOLARIS_11_B159_OR_LATER  was set or not.
