There is a race condition in the ProtonHandlerImpl.outputBuffer() method. The method checks to see how many bytes (n) are pending in the underlying ProtonJ buffer, then creates a Netty buffer of size n. It then writes the contents of the pending ProtonJ head. However, ProtonJ can still write to it's internal buffer, meaning that it's buffer.size > n causing an illegalArgumentException. This patch fixes it by only writing 'n' bytes to the Netty buffer. |

ActiveMQ Artemis
This file describes some minimum 'stuff one needs to know' to get started coding in this project.
Source
For details about the modifying the code, building the project, running tests, IDE integration, etc. see our Hacking Guide.
Building the ASYNC IO library
ActiveMQ Artemis provides two journal persistence types, NIO (which uses the Java NIO libraries), and ASYNCIO which interacts with the linux kernel libaio library. The ASYNCIO journal type should be used where possible as it is far superior in terms of performance.
ActiveMQ Artemis does not ship with the Artemis Native ASYNCIO library in the source distribution. These need to be built prior to running "mvn install", to ensure that the ASYNCIO journal type is available in the resulting build. Don't worry if you don't want to use ASYNCIO or your system does not support libaio, ActiveMQ Artemis will check at runtime to see if the required libraries and system dependencies are available, if not it will default to using NIO.
To build the ActiveMQ Artemis ASYNCIO native libraries, please follow the instructions in the artemis-native/README.
Documentation
Our documentation is always in sync with our releases at the Apache ActiveMQ Artemis website.
Or you can also look at the current master version on github.
Examples
To run an example firstly make sure you have run
$ mvn -Prelease install
If the project version has already been released then this is unnecessary.
Each individual example can be run using this command from its corresponding directory:
$ mvn verify
If you wish to run groups of examples then use this command from a parent directory (e.g. examples/features/standard):
$ mvn -Pexamples verify
Recreating the examples
If you are trying to copy the examples somewhere else and modifying them. Consider asking Maven to explicitly list all the dependencies:
# if trying to modify the 'topic' example:
cd examples/jms/topic && mvn dependency:list
