policy files which contain no restrictions on cryptographic strengths.

to provide the basic capability to download and unzip Oracle Java distributions

The module provides different classes to install Java OpenJDK 6, 7, 8 and 9; furthermore, it is possible to install Oracle JDK 7 and 8.

It is possible to install multiple versions of Java on a single node and to specify via hiera the default java to be set in the alternative system. An example hiera (JSON) declaration for a node could be as follows:

At the moment the module targets only OpenJDK 6, 7 and 8 on Debian, Ubuntu, RedHat and CentOS platforms. Specifically, it was tested on Ubuntu 12.04, 14.04, 16.04 and CentOS 6.6 distributions; although probably it will work also on different versions.
