    Description

      I have a Game Server made using Undertow WebSockets, which worked fine with Java 9, and is giving me problem with Java 11 (openjdk), on Centos 8.

      I profiled the server using JProfiler and the problematic method is different in 2.0.20.Final and in 2.0.29.Final, I'll attach screenshots of both.

      In 2.0.20 it's SSLEngineImpl.wrap()
      In 2.0.29 it's WebSocketChannel.lastDataRead()

      EDIT: See first comment.

          • Major - To be worked after higher priority work items are addressed. When the severity is high and the effort to change it is low to moderate, this term is chosen. Issues in this category likely have an existing workaround but implementation or execution may be non-trivial.
