tillrohrmann opened a new pull request #6867: [FLINK-10580] Harden BootstrapTool#startActorSystem
URL: https://github.com/apache/flink/pull/6867
   ## What is the purpose of the change
   Instead of opening a socket to check whether a given port is free we simply start an
   ActorSystem with it an check whether it can bind to this port. This also solves the problem
   that a 0 port get resolved to a specific port which might get taken between closing the
   test socket and starting the ActorSystem.
   ## Verifying this change
   - Added `BootstrapToolsTest#testConcurrentActorSystemCreation` which failed without this
change (non-deterministically)
