我在Wildfly 14中遇到以下错误：
19:21:02,947 ERROR [io.undertow] (default task-59) UT005085:

像这样将standalone.xml中的enable-http2属性从true更改为false后，它会起作用：
<https-listener name="https" socket-binding="https" security-realm="SslRealm" enable-http2="false"/>
另请参阅：

在Wildfly 10中，同一应用程序使用enable-http2 =“ true”设置。
Wildfly 14出现错误的原因是什么？我不能再在Wildfly 14中使用HTTP / 2还是解决该问题？
