Description

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.
