Hello,
When jshell or jjs are suspended and resumed, the terminal is reset to
un-raw/cooked mode and jline editing is not working properly (as that
requires raw mode). The solution I know about is to reset the terminal
to raw mode on resume. This can be achieved using
jdk.internal.misc.Signal (or sun.misc.Signal), which seems mostly fine
to me for jshell and jjs, as s.m.Signal is a critical internal API per
JEP 260. (Use of Signal would seem less fine to me in jdk.internal.le,
as Signal is still an internal API.)
