Find out how to identify the root cause of JVM Stop-the-World pauses with JDK Flight Recorder in Java 11.

As you know Apple has begun the transition from Intel x86_64 processors to ARM64-based Apple silicon chips in Mac computers. There are still many jokes about some software that is lacking from the platform. The real challenge is to roll out programs that use low-level knowledge of the operating system and processor.

Liberica Native Image Kit (Liberica NIK) is a utility that converts your JVM-based application into a fully AOT compiled native executable under the closed-world assumption with an almost instant startup time. It is based on the open source GraalVM Community Edition. Being compatible with various platforms, including lightweight musl-based Alpine Linux, this technology optimizes resource consumption and minimizes the static footprint.

JDK Flight Recorder (JFR) is a powerful diagnostic tool built into OpenJDK. In previous posts, I was focusing on using JFR together with JDK Mission Control, a visual front end. Besides out of box integration with JDK tools like Mission Control and `jcmd`, Flight Recorder has an API.

Plain text documents are timeless. The earliest ASCII documents ever written can still be opened, read, and modified today, on virtually any hardware, using any operating system, without any proprietary software, online service, or third-party conversion program. In stark contrast are document formats such as those produced by Microsoft Word, ClarisWorks, Lotus Manuscript, WordPerfect, WordStar, and most other word processors, whether discontinued or not.

In this post about JDK Flight Recorder and Mission Control, a powerful diagnostic and profiling tool built into OpenJDK, I would like to focus on JVM memory features.

Hunting down code hotspots is probably the most common task for Java profilers.
