Liberty Java Runtime - Websphere Release Change Management
The documentation is very clear on how to manage the different versions of the JRE , but do you know how Bluemix manages websphere release switching?
To be specific, if I run my Java application today on the current 8.5 web page, can I be sure that if websphere is upgraded to 9.x, I will still have access to 8.5?

You can choose between the current buildpack version and the previous version. If the previous buildpack is based on an older version of Liberty, you can get the back-end Liberty. However, this will be temporary until another version of buildpack is released. There is no permanent guarantee that you will have access to older versions of Liberty, unless implemented by buildpack - as an option to choose the Liberty beta. Be in touch.
Command
'cf buildpacks' will show you all buildpacks.
