JDK 9 is out! But as a library writer, this means change, and change can go either way... Once we've satisfied that JCTools works with JDK9, what other observations can we make? Well, one of the main motivations for using JCTools is performance, and since the code has been predominantly tested and run with JDK8, is it even better with JDK9? is it worse?| Psychosomatic, Lobotomy, Saw

I've been giving a couple of talks in the last year about profiling and about the JVM runtime/execution and in both I found myself coming up against the topic of Safepoints. Most people are blissfully ignorant of the existence of safepoints and of a room full of people I would typically find 1 or 2 developers who would have any familiarity with the term. This is not surprising, since safepoints are not a part of the Java language spec. But as safepoints are a part of every JVM implementation ...| Psychosomatic, Lobotomy, Saw
Continuing from previous post on the expansion of the Queue interface to support new ways of interacting with queues I have gone ahead and implemented relaxedOffer/Poll/Peek for the JCTools queues.

Implementing batch/continuous interactions was a bit more involved, but the results were interestingly rewarding. I will save discussing the drain/fill res...| Psychosomatic, Lobotomy, Saw

Some years back I was working on a latency sensitive application, and since latency was sensitive it was a requirement that we somehow capture latency both on a transaction/event level and in summary form. The event level latency was post processed from the audit logs we had to produce in any case, but the summary form was used for live system monitoring. We ended up with a solution I've seen since in many places (mild variations on a theme), which is what I've come to think of as the linear ...| Psychosomatic, Lobotomy, Saw
