The only times I see NIO go awry these days is in the async code and that is as complex as it is partly to support the continued use of BIO. There was a small hack in 7.0.x for async processing, a larger hack in 8.0.x for non-blocking I/O. I suspect an even bigger hack would be required in 9.0.x. If folks don't need async features and want to use BIO simply use Tomcat 8. Based on the typical life time of a major Tomcat version that is likely to be around for a good few years yet. The connector code is complex and suffers from large amounts of copy / paste / edit. One of my goals with 9.0.x is to simplify the code, reduce the duplication and make the async code more robust. Removing BIO and Comet are part of that.
