Do Java 6 threading optimizations actually work? - Part II
Features like biased locking, lock coarsening, lock elision by escape analysis and adaptive spin locking are all designed to increase concurrency by allowing more effective sharing amongst application threads. But do they actually work? In this two part article, Jeroen Borgers explores these features and attempt to answer the performance question with the aid of a single threaded benchmark.

Real-Time Java for the Enterprise
Simon Ritter explains the vision and capabilities of the Real-Time Java specification (RTSJ), if your Java app really, really must respond within a certain time regardless of what the garbage collector does, RTSJ is now a possibility rather than a probability.

The Box: A Shortcut to finding Performance Bottlenecks
Finding performance bottlenecks can be a difficult task and it can get even more difficult as our applications grow in size. The Box is a methodology tool that focuses us efforts to improve performance.If you want to be consistent and predictable, getting rid of the guessing is a must.

Introduction to OpenTerracotta
OpenTerracotta is an open source enterprise-class JVM clustering solution that can take multi-threaded single-JVM apps and have them run across multiple JVMs with no code changes. Orion Letizi goes super-indepth on Terracotta and how it works, explaining how to do session replication, distributed caching, master/worker, and more.

In-process Interoperability
The two most popular managed environments (the JVM and the CLR) are in fact, nothing more than a set of shared libraries, each providing services to executing code such as memory management, thread management, code compilation (JIT), etc. Using both the JVM and the CLR inside the same operating system process is easy, since any process is capable of loading just about any shared library.
