> When using JMS streaming, an ArrayOutOfBoundsException occurs in ActiveMQInputStream
if the length of the streamed content is exactly a multiple of the chunk size sent by ActiveMQOutputStream
(64KB at the moment).
> The last message received by fillBuffer in such a case has a bodyLength of 0, so
>   buffer = new byte[0]; // line 225
>   pos = 0; // line 227
> and in the next invocation of read()
>   return buffer[pos]; // line 180
> fails with:
>   java.lang.ArrayIndexOutOfBoundsException: 0
> 	at org.apache.activemq.ActiveMQInputStream.read(ActiveMQInputStream.java:180)
> 	at Crash.main(Crash.java:54)
> Attached is Crash.java which produces the exception.
