quarkus: IllegalReferenceCountException logged with enabled compression

Hi

Describe the bug I’m seeing this in 1.11.1.Final after enabling compression via quarkus.http.enable-compression:

2021-01-29 07:19:42,608 WARN  [io.net.cha.ChannelOutboundBuffer] (vert.x-eventloop-thread-4) Failed to mark a promise as success because it has failed already: DefaultChannelPromise@3d236c66(failure: io.netty.handler.codec.EncoderException: io.netty.util.IllegalReferenceCountException: refCnt: 0, decrement: 1), unnotified cause:: io.netty.handler.codec.EncoderException: io.netty.util.IllegalReferenceCountException: refCnt: 0, decrement: 1

Expected behavior There should be no exception logged as the content is transfered without any problem.

To Reproduce

Steps to reproduce the behavior:

1. Enable compression
2. Access a (reactive [Mutiny]?) endpoint

I’ll try to create a reproducer if needed be.

Configuration

quarkus:
  http:
    auth:
      proactive: true
    cors:
      ~: true
      origins: http://localhost:3000
      methods: DELETE, GET, POST, PUT, OPTIONS
    root-path: /
    limits:
      max-body-size: 20480K
    enable-compression: true
  resteasy:
    gzip:
      enabled: true
      max-input: 20480K

Environment (please complete the following information):

• Output of uname -a or ver: Linux voyager 5.10.11-arch1-1 #1 SMP PREEMPT Wed, 27 Jan 2021 13:53:16 +0000 x86_64 GNU/Linux

• GraalVM version (if different from Java):
• Quarkus version or git rev: 1.11.1.Final
• Build tool (ie. output of mvnw --version or gradlew --version):

Additional context

• Adding “quarkus-undertow” dependency like stated in #9194 does not remove the exception.
• Disabling compression removes the exception.

/edit: fixed the statement about the tried workaround – it’s not working.
