> Some keys like key down are composed from multiple characters. Normally when the key down is pushed, 3 characters are written into stdin. These 3 characters are read by InputStream::read operation at once and then decoded to the Key.DOWN constant.
> However there is no guarantee that InputStream::read operation returns all the 3 characters at once. It can return only first character and then remaining two. This actually happens in one test on Solaris and HPUX, where stdin is emulated by PipedInputStream.
> If the aforementioned situation happens, pushing of key down is decoded as pushing of two maybe three keys - ESC and some other key(s).
> The issue has low priority, because this behavior wasn't observed in real terminal with real input. It affects only testing.
