Common Java functionality for core functionality.

jerry-core is a module library for the uber jerry library project. This module provides core functionality as static helper utility classes that can help reduce the boiler plate code when making even a simple Java application.

The core idea of the project is to include all basic functionality that is always used in a normal project. The project does not aim to replace the Apache Commons framework but only extend it to include the otherwise useful functions and methods that are missing in there.

History: Ages ago, the project forked from the https://github.com/sangupta/jerry project, when all utility classes were extracted out into the jerry-core project.

The library is tested on the following JDK versions:

  • Oracle JDK 9
  • Oracle JDK 8
  • Oracle JDK 7
  • Open JDK 7
