B4J Library jServer v4.0 - Based on Jetty 11

Starting from B4J v9.80 this library is included as an internal library. Old library: https://www.b4x.com/android/forum/threads/141323/#content
This is a new version of jServer. It is based on Jetty 11.0.9. Previous versions were based on an early version of Jetty 9.
There were many improvements in Jetty during the last couple of years: https://github.com/eclipse/jetty.project/releases

It requires Java 11+.
It works with the standalone packager with these declarations:

#PackagerProperty: AdditionalModuleInfoString = provides org.slf4j.spi.SLF4JServiceProvider with org.eclipse.jetty.logging.JettyLoggingServiceProvider;
#PackagerProperty: AdditionalModuleInfoString = provides org.eclipse.jetty.io.ssl.ALPNProcessor.Server with org.eclipse.jetty.alpn.java.server.JDK9ServerALPNProcessor;
#PackagerProperty: AdditionalModuleInfoString = provides org.eclipse.jetty.http.HttpFieldPreEncoder with org.eclipse.jetty.http2.hpack.HpackFieldPreEncoder, org.eclipse.jetty.http.Http1FieldPreEncoder;
#PackagerProperty: AdditionalModuleInfoString = uses org.eclipse.jetty.util.security.CredentialProvider;
#PackagerProperty: AdditionalModuleInfoString = uses org.eclipse.jetty.io.ssl.ALPNProcessor.Server;
#PackagerProperty: IncludedModules = jdk.charsets, jdk.crypto.ec
#CustomBuildAction: After Packager, %WINDIR%\System32\robocopy.exe, www temp\build\bin\www /E

Note that http sessions are not created automatically for WebSockets. You can use this filter handler to create it: https://www.b4x.com/android/forum/threads/safari-session-variables-in-b4j-v4.61652/post-389898 (apparently it relied on a feature not supported by WebSocket specs).

b4j_ws.js v0.93 is attached. It includes a fix suggested by @alwaysbusy: https://www.b4x.com/android/forum/threads/jserver-v4-0-based-on-jetty-11.140437/post-889892

Updates:
- v4.03 - suppresses the stack trace logs for ClosedChannelExceptions, which can happen sporadically on disconnections.

Hi, how can i use 4.0.3 wrapper for jServer.
I have a strange error that even ChatGPT can't resolve.
Even if I don't write any resp and I use resp.SendRedirect inside a Wait For Job I get error 500 and I'am very frustrated that I can't resolve this error.
I'm trying to autenticate on Azure and I have this error on callback url

Any error you encounter will not be solved with v4.03.

Start a new thread and provide more information.
