Java 9 provides a common logging system for JVM components with extremely detailed level, an infrastructure to do the logging. With new command-line option
-Xlog for all logging followed settings, Unified JVM Logging gives us a precise, easy-to-configure tool to do a root cause analysis of complex system-level JVM components.
Javadoc is the tool that can generate documentation for API in HTML format. In previous version of JDK, it’s HTML 4.01 – an old standard. JDK 9 Javadoc now supports to generate HTML5 markup, improves search capability and Doclint.
Internationalization Enhancements for JDK 9 include: Unicode 8.0, UTF-8 Properties Files and enabling CLDR Locale Data by Default.
In earlier version of Java, Image I/O Framework
javax.imageio provides a standard way to plug-in image codecs for some formats such as PNG and JPEG. But TIFF is still missing from this set. It was packaged in
com.sun.media.imageio.plugins.tiff before. Java 9 TIFF Image I/O plugins has a new package called
javax.imageio.plugins.tiff which is renamed from
In this article, we’re gonna take a look at that package and test a simple example.
