to put the test in the appropriate directory, id have to java files to
grade build configs, because it currently only checks for kotlin tests.

create a temp zip file > create a destination that is a file not a
directory (guaranteed exception) -> unzip throws ioexception because it
expects a directory not a file -> catch it -> check if the zip file is
still open -> if true == leak.

Ive also removed the test since its OS specific, and new code is
supposed to be in kotlin.

Moved the undecorated setup to the very beginning of the Editor
constructor before any operations that could make the frame displayable
happened.
