Motivation:
The toString() methods of MqttSubscribePayload and MqttUnsubscribePayload are causing exceptions when no topics are set.
Modification:
The toString() methods will not throw Excpetions anymore.
Result:
Fixes#9197
Motivation:
Most of the maven modules do not explicitly declare their
dependencies and rely on transitivity, which is not always correct.
Modifications:
For all maven modules, add all of their dependencies to pom.xml
Result:
All of the (essentially non-transitive) depepdencies of the modules are explicitly declared in pom.xml
Motivation:
When the MqttDecoder decodes a message larger than the 'maxBytesInMessage' a DecoderException is thrown and a MqttMessage with just the failure cause is returned. Even if I can't handle the message, I might want to send an ACK so that I won't have to worry about it again.
Modification:
The DecoderException is thrown after the variableHeader is decoded. The fixed and variable headers are then added to the MqttMessage along with the failure cause.
Result:
The invalid MqttMessage will have headers if available.
Since 3.1.1 mqtt protocol version SUBACK message can now indicate the failure in payload.
Modification:
Do not erase failure payload in for SUBACK message.
Result:
Fixes#7665
Automatic-Module-Name entry provides a stable JDK9 module name, when Netty is used in a modular JDK9 applications. More info: http://blog.joda.org/2017/05/java-se-9-jpms-automatic-modules.html
When Netty migrates to JDK9 in the future, the entry can be replaced by actual module-info descriptor.
Modification:
The POM-s are configured to put the correct module names to the manifest.
Result:
Fixes#7218.
Motivation:
The MQTT decoder should raise an exception trying to build a CONNECT packet where password field is set but not the username one (as by MQTT 3.1/3.1.1 spec).
Modification:
Throw exception if password field is set but not the username
Result:
Fixes [#7205].
