Update the Java part to latest dependencies

[gregorwolf]

I've disable the Java part as the used dependencies where outdated.

I try to get it working again but the samples provided by the SAP Documentation are a mess. They work all just with manifest.yml and do not provide an easy to deploy mta.yaml. Here is my collection:

• Tutorial: Create a Sample Application on Cloud Foundry Using SAP Cloud SDK
• Tutorial: Create an Application with SAP Java Buildpack
• Documentation: Developing Java in the Cloud Foundry Environment
• Documentation: Invoke ABAP Function Modules in On-Premise ABAP Systems
