Option to silently ignore any exceptions, or show them in non-blocking way

[anonymous]

As workaround for #5925 (or any similar bugs) there should be option that will allow JOSM to silently ignore any exception (or report them in manner not interfering with work, like showing small notice in part of statusbar, logging them to some file, etc ...)

This is a wontfix. Exceptions are programm states, which are unexpected and should not happen. We can't and wont ignore them silently. Everything which can be catched is catched or will be catched and handled properly.
