Known Issues / Arbitrary Decisions
obviously expected behavior did not happen or when a specification was
ambiguous. This section describes such issues.
- - The JVM needs some warmup time to exhibit the true performance
- behavior. Drag a window around for a bit to see this: the initial
- performance is slow, then the JIT compiler kicks in and Jexer can
- be visually competitive with C/C++ curses applications.

SetConsoleMode()).
- - TTerminalWindow launches 'script -fqe /dev/null' or 'script -q -F
- /dev/null' on non-Windows platforms. This is a workaround for the
- C library behavior of checking for a tty: script launches $SHELL
- in a pseudo-tty. This works on Linux and Mac but might not on
- other Posix-y platforms.

- Closing a TTerminalWindow without exiting the process inside it
may result in a zombie 'script' process.
- - TTerminalWindow cannot notify the child process of changes in
- window size, due to Java's lack of support for forkpty() and
- similar. Solving this requires C, and will be pursued only if
- sufficient user requests come in.
