Azul Zulu is an open source implementation of the Java Standard Edition ("SE")
specification. It is a binary build of the OpenJDK open source project.
Zulu provides a Java Runtime Environment needed for Java applications to run.

Azul Zulu 8 implements the Java SE 8 specification from Oracle.



A Zulu deployment consists of a Zulu JDK:

juju deploy zulu8

The Zulu charm adds a public key for the Azul apt-get repository to your system,
then installs Zulu-8 from it.

The Zulu charm also sets Zulu-8 as default java using update-alternatives.

Once deployed you can use Zulu to run any Java workloads.

Java Debugger (JDB)

Remote debugging can be useful for application development and diagnosing
problems with a deployed application. There are many debugging tools,
including jdb, and most Integrated Development Environments (IDEs) provide
the ability to attach to remote servers and step through code line by line.
