List of new command-line tools part of jdk-9:
Tool Notes Link
jaotc Ahead-of-Time (AOT) compilation to boost the start-up time of small and large Java applications, with at most a limited impact on peak performance, https://jaxenter.com/java-9-will-support-ahead-time-compilation-129874.html
jcontrol The Java Control Panel is used to control how Java and JavaFX applications that are embedded in a browser or are launched from a browser run on your computer. https://docs.oracle.com/javase/9/deploy/java-control-panel.htm
jdeprscan You use the jdeprscan tool as a static analysis tool that scans a jar file (or some other aggregation of class files) for uses of deprecated API elements. https://docs.oracle.com/javase/9/tools/jdeprscan.htm
jhsdb You use the jhsdb tool to attach to a Java process or to launch a postmortem debugger to analyze the content of a core-dump from a crashed Java Virtual Machine (JVM). https://docs.oracle.com/javase/9/tools/jhsdb.htm
jimage There’s a “jimage” tool in the bin directory that is useful for troubleshooting, you can use this to list or expand for example. It’s not the full range of options that you have with the “jar” tool but that is mostly because the jimage format is intended to be JDK-internal and not something that most developers will interact directly with. This is the only link i found useful http://narkive.com/xjE5x0tf:3.341.341
jlink You can use the jlink tool to assemble and optimize a set of modules and their dependencies into a custom runtime image. https://docs.oracle.com/javase/9/tools/jlink.htm
jmod You use jmod to create JMOD files and list the content of existing JMOD files. https://docs.oracle.com/javase/9/tools/jmod.htm
jshell You use the jshell tool to interactively evaluate declarations, statements, and expressions of the Java programming language in a read-eval-print loop (REPL). https://docs.oracle.com/javase/9/tools/jshell.htm

Java SSL/TLS Testing Tool: Cipher Suite

-
Image
Recently I was reading about the TLS/SSL and Ciphers. I was also interested to read about the Ciphers that are provided out of the box with JDK. This looked to me like this is something we take it for granted and do not do our due diligence when talking about the Ciphers. We often times leave those topic to our organization's network and security team. From my experience, it is a topic that all the developers leave it to the Sr. Developers and then the Sr. Developers pass it on to the Management. Guess what? It is not a sweet topic to discussion. To break this kind of symptom, I have choose to make it simple and want everyone to understand the complexity and importance of knowing this. Lets get started Before we wet our hands here is some basic information that you will require to know, Word Meaning Protocol A defined set of rules and regulations that determine how data is transmitted in telecommunications and computer networking SSL ...

Yarn and Angular-CLI

Background I have been thinking of a faster package management tool ever since I started using NPM (Node Package Manager). Please don’t mistake me having anything against NPM. I still love this package manager and I very much love the rich command-line that it came with. When it was created, it was really the leader and because of this NPM the whole JS world has seen a revolution. NPM surly was the spark to the revolution in the JS (Java Script) world. To make it clear for everyone why we needed a new package manager is because of the following challenges that we had with NPM, 1.      The Nested dependencies that was sometimes going in infinity loops. At times, it was impossible to delete files on the PC as the paths were too nested. 2.      Everything on the world had to depend on only one registry. https://www.npmjs.com/ 3.      Single threaded installation. The installation of the dependencies are single thre...
