Hi, w/ Java8 and the Stream API, there is parallelStream(), which is based on the Fork-Join Pool. With JavaEE there a concurrency util, for managed threads and executors. However, fork-join is imcompatible with those managed threads, therefore I think (I hope I am not wrong here) it is NOT recommended to use parallel streams in JavaEE. Now, that WildFly-10 is Java8 and later I am wondering if there are plans to support that; e.g. with a non-standard feature/flag which could enable it, if desired. Sure that would cause issues regarding portablility, but still :-) Just wondering if there are any thoughts around this, for WildFly 10 or 11 Thanks, Matthias
