    That's why the pull request has the check for obsolete keys which fails to 
start Flink when old config entries are detected. In addition, it has sanity 
checks to check whether managed memory size < heap+offheap memory size. To make 
things clearer, we could use taskmanager.jvm.size (although the actual size 
depends on many other things).
