[Red Hat JIRA] (WFLY-14269) Wildfly 21's “allow-unescaped-characters-in-url” ignored when HTTP2 request going through Windows hosts file

[ https://issues.redhat.com/browse/WFLY-14269?page=com.atlassian.jira.plugi... ] Marton Csukas updated WFLY-14269: --------------------------------- Steps to Reproduce: * Have an entry in your Windows hosts file for the endpoint you are about to test, e.g.: {code:java} 127.0.0.1 myappname.company.com{code} * In standalone.xml have *allow-unescaped-characters-in-url=true* on *http-listener* and *https-listener* * In standalone.xml also have *enable-http2=true* on *http-listener* and *https-listener*** * On _Wildfly 21.0.0.Final_ send a GET request with at least one | (pipe) character in the query parameters * In latest Chrome (Version 87.0.4280.88 (Official Build) (64-bit)) or Firefox call a GET request with unencoded | (pipe) symbol in the query (e.g.: GET myappname.company.com/myAPI?someParam=customerId=1212090,caseId=1078841||...) * On Wildfly 21.0.× this will result in a ERR_HTTP2_PROTOCOL_ERROR, and a 4×× error code - with the request not even hitting the application - essentially allow-unescaped-characters-in-url is ignored * On Wildfly 20.0.× this works fine, as expected. * On Wildfly 21.0.× , when I remove *enable-http2*, or set it to false, it also works fine. If you remove the entry from the hosts file though, and the request goes through the company load balancer for myappname.company.com, the request will be successful. was: * Have an entry in your Windows hosts file for the endpoint you are about to test, e.g.: {code:java} 127.0.0.1 myappname.company.com{code} * On _Wildfly 21.0.0.Final_ send a GET request with at least one | (pipe) character in the query parameters * In latest Chrome (Version 87.0.4280.88 (Official Build) (64-bit)) or Firefox call a GET request with unencoded | (pipe) symbol in the query (e.g.: GET myappname.company.com/myAPI?someParam=customerId=1212090,caseId=1078841||...) * On Wildfly 21.0.× this will result in a ERR_HTTP2_PROTOCOL_ERROR, and a 4×× error code - with the request not even hitting the application * On Wildfly 20.0.× this works fine, as expected. * On Wildfly 21.0.× , when I remove *enable-http2*, or set it to false, it also works fine.
