[Rxtx] RXTX serial port read() returns -1 unexpectedly and then blocks forever on close()

[Michael Erskine]

So if -1 is unexpectedly returned from read, and we have demonstrated
that your USB-serial adapter can actually causes this to happen in
RXTX, why not just ignore the -1 value? What happens when you try
this? As for a hang on close, are your closing your port from within
your serial event handler? I know that this can cause some serious
problems.
