Jiri Danek created QPIDJMS-313:
----------------------------------
Summary: Message#getBody does not throw when attempting to read a
BytesMessage as String.class
Key: QPIDJMS-313
URL: https://issues.apache.org/jira/browse/QPIDJMS-313
Project: Qpid JMS
Issue Type: Bug
Components: qpid-jms-client
Affects Versions: 0.23.0
Reporter: Jiri Danek
Priority: Minor
Consider the ActiveMQ Artemis test
{{org.apache.activemq.artemis.tests.integration.jms.jms2client.BodyTest#testBodyConversion}}
adapted to run through multiple JMS ConnectionFactories in turn. This test
passes with Core JMS client, is skipped (or should be skipped) with ActiveMQ
OpenWire client (that is a JMS 1.1 client) and fails with qpid-jms client.
{noformat}
BytesMessage bytesMessage = sess.createBytesMessage();
producer.send(bytesMessage);
Message msg = cons.receiveNoWait();
assertNotNull(msg);
try {
msg.getBody(String.class);
fail("Exception expected");
} catch (MessageFormatException e) {
}
{noformat}
The failing line is the {{fail("Exception expected");}}, because qpid-jms does
not throw {{MessageFormatException}} where it is supposed to.
According to https://docs.oracle.com/javaee/7/api/javax/jms/Message.html. "If
the message is a BytesMessage then this parameter must be set to byte[].class
(or java.lang.Object.class). This method will reset the BytesMessage before and
after use." ... "Throws: MessageFormatException" ... "if the message body
cannot be assigned to the specified type."
