Eclipse OpenJ9 is a high performance, scalable, Java virtual machine (JVM) implementation that represents hundreds of person-years of effort. Contributed to the Eclipse project by IBM, the OpenJ9 JVM underpins the IBM SDK, Java Technology Edition product that is a core component of many IBM Enterprise software products. Continued development of OpenJ9 at the Eclipse foundation ensures wider collaboration, fresh innovation, and the opportunity to influence the development of OpenJ9 for the next generation of Java applications.
This is an example org.apache.camel.spi.RoutePolicy implementation that allows you to use a lock file to ensure a single instance of a route running in a cluster.
Spring Boot Admin – Admin UI for administration of spring boot applications | Java Code Geeks - 2017
As part of micro services development many of us are using Spring Boot along with Spring Cloud features. In micro services world we will have many Spring Boot applications which will be running on same/different hosts. If we add Spring Actuator to the Spring Boot applications, we will get a lot of out of the box end points to monitor and interact with Spring Boot applications. The list is given below.
A demo for using jasper within a Spring Boot App I made for a Jasper session.
This depicts integration of jasper reports within a spring boot app .
Mostly uses concept of JasperReportsViewResolver as defined here http://stackoverflow.com/questions/27532446/how-to-use-jasperreports-with-spring-mvc [Check the answer with the tick there :)]
Also the report included using my custom db and data so try putting your own .jrxml report there before trying to run.
The jasper endpoints shall be like http://localhost:8080/report/{reportname}?format={format}&id={id} (id param are optional,you can add ur custom report params there)
Cheers!

Spark Framework is a simple and lightweight Java web framework built for rapid development. Spark's intention isn't to compete with Sinatra, or the dozen of similar web frameworks in different languages, but to provide a pure Java alternative for developers that want to, or are required to, develop their web application in Java. Spark focuses on being as simple and straight-forward as possible, without the need for cumbersome (XML) configuration, to enable very fast web application development in pure Java with minimal effort. It’s a totally different paradigm when compared to the overuse of annotations for accomplishing pretty trivial stuff seen in other web frameworks, for example, JAX-RS implementations.

jGRASP is a lightweight development environment, created specifically to provide automatic generation of software visualizations to improve the comprehensibility of software. jGRASP is implemented in Java, and runs on all platforms with a Java Virtual Machine (Java version 1.5 or higher). jGRASP produces Control Structure Diagrams (CSDs) for Java, C, C++, Objective-C, Ada, and VHDL; Complexity Profile Graphs (CPGs) for Java and Ada; UML class diagrams for Java; and has dynamic object viewers that work in conjunction with an integrated debugger and workbench for Java. The viewers include a data structure identifier mechanism which recognizes objects that represent traditional data structures such as stacks, queues, linked lists, binary trees, and hash tables, and then displays them in an intuitive textbook-like presentation view.
