> In my tests syncing data to disk in commit thread failed (due to majority lost) causing
abort of pending commit jobs. IllegalStateException was reported IO-Threads waiting for commit
finish.
> try-catch blocks in ReplicatedEnvironmentFacade#commit and ReplicatedEnvironmentFacade#commitAsync
do not handle IllegalStateException on environment restart as in the rest of the code.
> Cathcing and handling all RuntimeExceptions should fix the issue
