JavaFx msal4j NoClassDefFoundError-CodePudding

I am running into an exception trying to get the example code here working with a JavaFx desktop app.

Java Version - OpenJDK 17 OS - Linux Mint 20.1 Ulyssa

My Azure app reg has been setup,

private String PUBLIC_CLIENT_ID = "my client id from azure";
private String AUTHORITY = "https://login.microsoftonline.com/organizations/";

My code is setup inside my Controller's constructor

    public HelloController() throws MalformedURLException, URISyntaxException {
        PublicClientApplication app = PublicClientApplication
                .builder(PUBLIC_CLIENT_ID)
                .authority(AUTHORITY)
                .build();

        InteractiveRequestParameters parameters = InteractiveRequestParameters
                .builder(new URI("http://localhost"))
                .scopes(Collections.singleton("user.read"))
                .build();

        IAuthenticationResult result = app.acquireToken(parameters).join();

    }

And gets this stack trace upon startup complaining about not being able to find com/sun/net/httpserver/HttpHandler

Exception running application com.example.fxtimer.HelloApplication

Process finished with exit code 1

If I do add that httpserver as a dependency

 <dependency>
            <groupId>com.sun.net.httpserver</groupId>
            <artifactId>http</artifactId>
            <version>20070405</version>
        </dependency>

I get a little further until something else is undefined. No browser window ever launches.

Exception running application com.example.fxtimer.HelloApplication

Process finished with exit code 1

Does anyone know what is causing this Class definitions to be missing/what I need to do in order to get everything working nicely?

Thanks for any help!

CodePudding user response：

You don't need to add a dependency for the http server, it is in the jdk.

Perhaps you need to require it as a module.

The Microsoft library should define a module-info.java file which appropriately defines the module and its requirements; however, it does not do so. Log a bug report in their issue tracker. You might be able to get it to work in a modular environment by some hacks or VM arguments or running stuff off the class path instead.

Try to replicate this behavior in a modular Java app (app with module-info.java), which does not use JavaFX, to create a minimal reproducible example, then edit the question to include your example and also put the example in your issue report to Microsoft.

The second exception you posted,

java.lang.ClassNotFoundException: sun.misc.ServiceConfigurationError

is because sun.misc APIs were never part of the public JRE API and several sun.misc APIs (including this one) were removed deprecated in JDK 9 and removed from the JDK as part of the modularity work.

The exception occurred because you tried to bring in a really old dependency on a 2007 version of the com.sun.net.httpserver API which is not compatible with Java 9 .
