  • [ ] Biased locking
  • [ ] synchronized usage analysis to find un-necessary usage in particular with respect to biased locking
  • [ ] define biased locking removal strategies for each of the various usage

[hakarim740-com-ra]

Can we have support for HTTP/3?

[vietj]

it shall be implemented but most likely in 5.x, x > 0

[hakarim740-com-ra]

it shall be implemented but most likely in 5.x, x > 0

Can we get vertx.createQuicServer() or QuicServer.create(vertx) too?
