Opening in IJ

JMC with IntelliJ

At this stage there’s two approach:

• If you only need to work on the core libraries, then you only need those, and they can be imported as a maven project with some configuration
• If you need the full blown JMC, then you need the other import approach, that is a mix of .project - .classpath and Maven projects.

Working on the on the core libraries

1. File | Open… , then select the core folder in the JMC cloned repository,
2. Trust the project (also tick the Trust projects in <JMC clone path> as well)

 * Exponential backoff counter implementing the Full Jitter algorithm from <a href="https://aws.amazon.com/blogs/architecture/exponential-backoff-and-jitter/">aws</a> by Marc Brooker.

 * <p>
 * The idea of backoff is to introduce a delay between retries, so that client don't compete
 * on the same resource. However it has been observed that clients may retry at the same time,
 * thus clustering calls on the same resource.

Nashorn is deprecated since Java 11, it has been removed in Java 15. In order to run javascript, it is necessary to upgrade the script engine. The most common alternative as of now is GraalVM JS engine.
