Marking as confirmed.  This should stick around until we actually implement it.

noting that 'clear -java' or equivalent is still not an option in Octave 6.4.0. It's been quite a while with 5 years since last commentary. Should status be changed or should it sit as a persistent reminder.

Ernst, please stop commenting here, if you think the description in bug #37971 is wrong, just add a comment there.

I understand this bug completely different,
namely as I described in #48850:
clear java refers to clearing the class, i.e. unloading.

This is a bug report just to track this issue and make sure it is not forgotten.

On a quick look, it doesn't look like it would be that difficult to implement.  One could loop over objects in the symbol table, call isjava() on them, and delete them or not based on that test.  It does look like a fair amount of C++ boilerplate code would be needed to accomplish that (nothing hard, but possibly tedious) as there would be modifying Fclear and adding a do_clear_java routine in variables.cc.  In symtab.h you would probably need a clear_java, clear_java_pattern, do_clear_java_pattern, clear_java_regexp, and do_clear_java_regexp routines.
