Jiri Danek created AMQ-6809:
-------------------------------
Summary: activemq-client return unexpected length code on first
read from stream containing empty byte array
Key: AMQ-6809
URL: https://issues.apache.org/jira/browse/AMQ-6809
Project: ActiveMQ
Issue Type: Bug
Components: JMS client
Affects Versions: 5.14.5
Reporter: Jiri Danek
Consider this code
{code}
private void testEmptyBufferInput() throws JMSException {
byte[] readList = new byte[BYTE_LIST.length - 1];
byte[] emptyList = {};
LOG.info("Streaming BYTE_LIST message testing EMPTY buffer
input");
stream.writeBytes(emptyList);
stream.reset();
LOG.info("Reading BYTE_LIST message testing EMPTY buffer
input");
final int IS_EMPTY = 0;
assertThat(stream.readBytes(readList)).isEqualTo(IS_EMPTY);
}
{code}
The code above works with qpid-jms, but fails with activemq-client on the
{{assertThat}} with error message {{java.lang.AssertionError: Not true that
<-1> is equal to <0>}}. Judging by documentation
http://docs.oracle.com/javaee/6/api/javax/jms/BytesMessage.html#readBytes(byte[]),
I think that qpid-jms behavior is correct and what activemq-client does is a
bug.
