[java] improve inner loop around configuration of SDKs

[akosyakov]

It would be nice if we can detect whether SDK required to run the project is pinned in the workspace configuration via Dockerfile instead of using the default workspace image. We could do it by using IDEs to detect SDK configured by projects at runtime and then comparing with one in the workspace image by statically analysing .gitpod.yml/Dockerfile or emulating the workspace using docker and performing detection using IDEs against there.
