> JShell prints some of its output using `printf()` formatted strings. However, there are a few spots where a string `str` to be printed is passed directly as a format string like `format(str)` instead of indirectly like `format("%s", str)`, even though the string `str` contains unknown or arbitrary content outside of JShell's control. As a result, JShell can crash suddenly with a `MissingFormatArgumentException` or similar exception if the string `str` happens to contain a `%` format specifier, etc.
