The Java Memory Model (JMM) defines the allowable behavior of multithreaded programs, and therefore describes when such reorderings are possible. It places execution-time constraints on the relationship between threads and main memory in order to achieve consistent and reliable Java applications.
Memory consistency model - To achieve scaling performance on many processors, it is important to exploit the "relaxed" Java Memory Model. Presently no JVM implements the JMM faithfully, and indeed many implement it incorrectly, leading to lack of coherence and loss of optimization opportunities. The specification of the JMM was also revised in ...
The Jakarta Messaging API (formerly Java Message Service or JMS API) is a Java application programming interface (API) for message-oriented middleware. It provides generic messaging models, able to handle the producer–consumer problem , that can be used to facilitate the sending and receiving of messages between software systems . [ 1 ]

Since JDK 1.2, Java has included a standard set of collection classes, the Java collections framework Doug Lea , who also participated in the Java collections framework implementation, developed a concurrency package , comprising several concurrency primitives and a large battery of collection-related classes. [ 19 ]
Modern programming languages like Java therefore implement a memory model. The memory model specifies synchronization barriers that are established via special, well-defined synchronization operations such as acquiring a lock by entering a synchronized block or method. The memory model stipulates that changes to the values of shared variables ...
HornetQ is an open-source asynchronous messaging project from JBoss.It is an example of Message-oriented middleware.HornetQ is an open source project to build a multi-protocol, embeddable, very high performance, clustered, asynchronous messaging system.
Java applications that use AMQP are typically written in Java JMS. Other implementations provide APIs for C# , C++ , PHP , Python , Ruby , and other programming languages . The High Level Architecture (HLA IEEE 1516) is an Institute of Electrical and Electronics Engineers (IEEE) and Simulation Interoperability Standards Organization (SISO ...
