AudioFormat does not handle uncommon bit sizes correctly

if you want to create e.g. a mono PCM AudioFormat with 18 bits sample size, the frame size should be 3 bytes. But the second constructor of AudioFormat creates an instance of AudioFormat with a 2 byte frame size.

The following code demonstrates the problem:

int bits = 18;
AudioFormat format = new AudioFormat(44100.0f, bits, 1, true, false);
if (format.getFrameSize() * 8 < bits) {
System.out.println("bits = "+bits+" do not fit into a "+format.getFrameSize()+" bytes sample!");
throw new Exception("Test failed");
} else
System.out.println("bits = "+bits+" fit OK into a "+format.getFrameSize()+" bytes sample!");
System.out.println("Test passed");
