Bugfixes
#1700 Pipe source resumed from wrong thread when passing response body from Vert.x HttpClient to CXF
In Quarkus CXF versions 3.18.0 (and possibly earlier), CXF clients based on Vert.x HTTP client froze sometimes, especially when receiving larger response bodies. The issue was caused by the fact that an internal class of Quarkus CXF, in an attempt to implement a standard Vert.x backpressure, was resuming a Vert.x Pipe from a worker thread instead of Vert.x Event Loop. That might sometimes have failed to awake the Pipe source from the paused state. Due to that, the consuming thread would keep waiting for input forever.
Check #1700 for more details.
#1636 FastInfosetTest.fastInfoset fails intemittently
When using FastInfoset serialization format, the InputStream from which CXF is reading the service response,
is first closed by the deserialization layer,
but then, the HTTP layer tries to read all unconsumed data from it
and closes it once again.
VertxHttpClientHTTPConduit was not able to handle that sequence of operations properly.
After the first close, the subsequent read hanged sometimes waiting for more input,
when the producer was finished already.
Check #1636 for more details.
