Not able to connect to server

[GoldenGamerLP]

Actual behavior (the bug) When trying to connect via https/ssl the server throws an error, and the client gets a 525 error code.

Error: java.nio.channels.SocketChannel[closed]: java.lang.IllegalStateException: Connection rejected: No ALPN Processor for sun.security.ssl.SSLEngineImpl

Expected behavior The client should be able to connect without problems, and no problems should occour on the server side.

To Reproduce Unforntatley the project is private, but i can share the depedencies.

Gradle:

 plugins {
    id 'java'
    id "com.github.johnrengelman.shadow" version "8.1.1"
}

group = 'me.alex'
version = '1.0-SNAPSHOT'

repositories {
    mavenCentral()
    maven { url 'https://jitpack.io' }
}

dependencies {
    implementation ('com.github.GoldenGamerLP:DependencyLoader:eed2460e41') {
        exclude module: 'DependencyExamples'
    }

    annotationProcessor('com.github.GoldenGamerLP:DependencyLoader:eed2460e41') {
        exclude module: 'DependencyExamples'
    }

    implementation 'org.slf4j:slf4j-simple:2.0.7'
    //Javalin
    implementation 'io.javalin:javalin:5.6.2'

    implementation 'com.github.HttpMarco:Aeon:-SNAPSHOT'
    //JsonParser
    implementation 'com.google.code.gson:gson:2.8.8'

    //Lombok
    implementation 'org.projectlombok:lombok:1.18.28'
    annotationProcessor 'org.projectlombok:lombok:1.18.28'
    //OpenAPI
    compileOnly 'io.javalin.community.openapi:javalin-openapi-plugin:5.6.2'

    implementation 'io.javalin.community.ssl:ssl-plugin:5.6.2'

    implementation ('org.eclipse.jetty:jetty-nosql:11.0.15') {
        exclude group: 'org.mongodb'
    }

    implementation 'org.mongodb:mongodb-driver-sync:4.6.0'
}

//Manifest
jar {
    manifest {
        attributes(
                'Main-Class': 'me.alex.app.street14endpoint.EndpointBootstrap',
                'Multi-Release': true
        )
    }
} 

Additional context I used a pem certificate with ssl forwarding. If you have anymore questions, feel free to ask.

I fixed the same issue by adding this line to my dependencies: implementation 'org.eclipse.jetty:jetty-alpn-java-server:11.0.18'

It might be a problem with the dependency imported by Javalin-SSL.

Discussed in Discord. Used custom classloading breaking Jetty's runtime Provider dependency loading.
