Bug with HTTP trailers and GZIP compression? #2562
Description
Hi guys,
I think I might have found a bug in Vert.x 3.5.3 or Netty. If I enable GZIP compression on both my HTTP server and the client and then try to send an HTTP trailer I get the exception below.
I created a gist demonstrating the error:
https://gist.github.com/michel-kraemer/382ef926d5503541fa1458d2e7695987
As soon as I comment out one of the lines marked with // XXXXXXX the program works correctly.
Am I doing something wrong or is this actually a bug?
Cheers,
Michel
