Forward or Redirect response sent to client before filter and request execution completes on EAP 7

Issue

• We see a behavior change moving from EAP 6 to EAP 7. We call a filter and servlet and the servlet forwards the request or calls response.sendRedirect. With EAP 6, the resulting was response was sent to the client after the filter and any other request execution completed. But with EAP 7, the client sees the resulting forward/redirect response immediately, before the filter or all other request execution completes. This causes an issue because our filter does important operations in a finally block after the chain.doFilter call, which the subsequent requests depend on.
