Java_java_io_Console_echo looks like this:
JNIEXPORT jboolean JNICALL
Java_java_io_Console_echo(JNIEnv *env, jclass cls, jboolean on)
{
DWORD fdwMode;
jboolean old;
...
old = (fdwMode & ENABLE_ECHO_INPUT);
...
return old;
}
It only works by accident. jboolean is an unsigned byte. ENABLE_ECHO_INPUT on the systems I know of is 0000010, so fdwMode & ENABLE_ECHO_INPUT fits into the result. We should do things properly and return a clean boolean.
