How much difference can thread affinity make?

In the past when I have performed performance tests using thread affinity, at best, it didn't appear to make much difference. I recently developed a library to use thread affinity in a more controlled manner, and another library which makes use of threads working together in a tightly coupled manner. The later is important because it appears to me that affinity makes the most difference when you have tightly coupled threads.

Fault Injection into Unit Tests with JBoss Byteman

How do you test error handling in your application? Do you? Is it at all possible to simulate SocketTimeoutException, SQLException?

Java Reflection in Action: Still Relevant After Eight Years

The book Java Reflection in Action was published in 2004, but remains largely applicable eight years later. In this post, I review this book and cover its strengths and its weaknesses. In general, age is the common theme of most of its weaknesses, but I was surprised at how relevant its information still is. The book was written when JDK 1.4 was the commonly used release of Java and J2SE 5 was well on its way (released late September 2004). Given this relative timing, it's obvious that where this book suffers is in coverage of reflection-related features made available after the release of JDK 1.4.
