Add support for java9+

[gberche-orange]

expected behavior

As a cf-java-client user

• in order to leverage java9+ language features
• I need cf-java-client to be compatible with java9+ LTS version, such as java11

observed behavior

• cf-java-client seems only tested in its ci against java8
  

  cf-java-client/ci/unit-test.yml

  Lines 4 to 8 in a83ea56

  	image_resource:
  	type: registry-image
  	source:
  	repository: openjdk
  	tag: 8-jdk

• cf-java-client running with java14 fails with the following stack trace, with root cause Deterministic Base64 support jwtk/jjwt#333 (comment) fixed in 0.10.0 while cf-java-client still uses 0.9.1

I'm almost done making the necessary changes for this, but need to put out a release today. I'm planning another release next week once Spring Boot updates, and this will be in that release!

[gberche-orange]

awesome, thanks @twoseat !

[twoseat]

@gberche-orange This is working its way through CI at the moment. I'd appreciate it if you could take a look once the build snapshot is available and make sure you're happy. Thanks!

[twoseat]

Update: We're having problems uploading artefacts, so you may want to leave this until Wednesday!

[twoseat]

Available now.
