NPE in AnnotatedEndpoint with version 2.0.0 when no ServerEndpoint is configured

[apupier]

I tried to migrate from previous version to 2.0.0, I replaced all javax.websocket to jakarta.websocket and I'm hitting this NPE:

[java.lang.NullPointerException

Here is the branch that I'm using https://github.com/apupier/camel-language-server/tree/tyrus.version-2.0.0-bugreport

Here is my ServerApplicationConfig class:

package com.github.cameltooling.lsp.internal.websocket;

import java.util.Collections;
import java.util.Set;

import jakarta.websocket.Endpoint;
import jakarta.websocket.server.ServerApplicationConfig;
import jakarta.websocket.server.ServerEndpointConfig;

public class CamelLSPWebSocketServerConfigProvider implements ServerApplicationConfig {

    private static final String WEBSOCKET_CAMEL_SERVER_PATH = "/camel-language-server";

    @Override
    public Set<ServerEndpointConfig> getEndpointConfigs(Set<Class<? extends Endpoint>> endpointClasses) {
        ServerEndpointConfig conf = ServerEndpointConfig.Builder.create(CamelLSPWebSocketEndpoint.class, WEBSOCKET_CAMEL_SERVER_PATH).build();
        return Collections.singleton(conf);
    }

    @Override
    public Set<Class<?>> getAnnotatedEndpointClasses(Set<Class<?>> scanned) {
        return scanned;
    }

}

the NPE is cause because the creation fo the configuration endpoitnConfig is failing. There is an error because my ServerEndpoint was still using javax.* (but cannot change directly as it is inherited from another library)

SO there is a problem of configuration but it woudl be nice to avoid the NPE so that the ErrorCollector can deliver what the issue is.
