How to use the P3D Renderer while using Processing in Intellij

I am trying to render a sketch with IntelliJ however when I select the P3D renderer mode, the program throws an error. I assume it has something to do with OpenGL, but I cant find anything about it online. Code is below.
import processing.core.PApplet;
public class GUI extends PApplet {
public GUI() {
}
public void settings() {
System.setProperty("jogl.disable.openglcore", "false");
fullScreen(P3D);
}
public void draw() {
background(0);
ellipse(mouseX, mouseY, 20, 20);
}
public static void main(String... args) {
PApplet.main("GUI");
}
}
The error is
java.lang.NoClassDefFoundError: com/jogamp/opengl/GLException

Getting The URL of Resource in Another Module

I am writting a library to ease the development of JavaFX application, and in order to make it usable with Java modular system, I need to get the URL of the FXML file in another java module (the client module) and pass it to FXMLLoader in my library (the library module).
So to sum:
I need to get the resource URL of an FXML file in the client module to be read in the library module.
I tried:
Accessing resource files from external modules
Load a Resource from another Module in Java (With Maven)
My latest attempt:
private void addController(ControllerInfo info, Class<? extends SimpleController> controllerClass) throws IOException {
String filename = info.FXMLFile();
if (!filename.startsWith("/"))
filename = "/" + filename;
ModuleReference ref=ModuleLayer.boot().configuration().findModule(moduleName).map(ResolvedModule::reference).get();
ModuleReader resReader=ref.open();
URL url = resReader.find(filename).get().toURL();
controllerClasses.put(info.Id(), controllerClass);
info.Type().getAction().addController(info, url, controllerClass);
}
In the client module I have placed my resources inside a io/github/ossnass/languageexample folder in the resources folder, and the module-info.java looks like this:
module languageExample {
requires javafx.controls;
requires javafx.fxml;
requires simplefx;
opens io.github.ossnass.languageexample.gui to javafx.fxml;
opens io.github.ossnass.languageexample to simplefx;
exports io.github.ossnass.languageexample.app;
}
The FXML contoller class:
#ControllerInfo(Id = "LangMain", FXMLFile = "/io/github/ossnass/languageexample/langexample.fxml", Type = ContollerType.SINGLE_INSTANCE_ON_STARTUP)
public class LangExampleMain extends SimpleController {
#Override
protected void userInit() {
}
#Override
protected void onStageShowUser() {
}
#FXML
private Button btnMessage;
#FXML
void btnMessageClick(ActionEvent event) {
QuickActions.showInfoMessage(null,
resources.getString("InfoHeader"),
resources.getString("InfoBody"),
this);
}
}
I get the following error:
java.lang.reflect.InvocationTargetException

The URL path to the resource file is :/io/github/ossnass/languageexample/langexample.fxml
Please notice that I am using Maven and I put the FXMLs in the resources dir.
The library I am developing can be found at SimpleFX

I was able to solve the problem using ClassGraph library with some help of how to properly make the URL from VGR
The following bit of code solved all (Java 8 and Java 9+ with modular system):
public static Resource getRescoure(String urlStr) {
try (ScanResult scan = new ClassGraph().scan()) {
if (urlStr.startsWith("/"))
urlStr = urlStr.substring(1);
ResourceList rl = scan.getResourcesWithPath(urlStr);
if (rl.size() > 0)
return rl.get(0);
return null;
}
}

Running Slick2D results in NoClassDefFoundError

I have tried to run a simple game using Java and keep getting an error when I try to run this application.
Exception in thread "main" java.lang.NoClassDefFoundError: sun/misc/Unsafe ...
I think my problem is that my JDK (12.0.2) does not support these Slick2D as it is "OutDated". If downgrading my Java Version is a solution can someone please explain how I can find a version of Java that supports Slick2D?
I have already set up my libraries in my IDE and set my path. I tried to run the same application in the newest Intellij and eclipse environments. I currently have JDK 12.0.2 installed and a 2015 version of LWJGL plus Slick2D installed.
package classPackage;
import org.newdawn.slick.*;
public class Game extends BasicGame{
public Game(String gamename) {
super(gamename);
}
#Override
public void init(GameContainer gc) throws SlickException {
}
#Override
public void update(GameContainer gc, int i) throws SlickException {
}
#Override
public void render(GameContainer gc, Graphics g) throws SlickException {
g.drawString("Howdy!", 10, 10);
}
public static void main(String[] args) {
try {
AppGameContainer appgc;
appgc = new AppGameContainer(new Game("Simple Slick Game"));
appgc.setDisplayMode(640, 480, false);
appgc.start();
} catch (SlickException ex) {
}
}
}

I was able to get this issue resolved by downgrading my jdk to 8. Thank you all I hope this will help someone in the future.

The NullPointerException error is at almost impossible location:
static {
ClassLoader cl = DefaultListableBeanFactory.class.getClassLoader();
try {
javaxInjectProviderClass = cl.loadClass("javax.inject.Provider"); /* line 108 */
} catch (ClassNotFoundException ex) {
// JSR-330 API not available - Provider interface simply not supported then.
}
}
This means that the class is not able to get its own classloader. You must have done something really bad to get this error. Check your JRE/JDK, IDE, ...
UPDATE
There is no explanation other than that you are probably trying to put Spring JARs into JRE's library folder (${java.home}/jre/lib). If that is the case, that is simply wrong. If you really want to include external JARs within JRE, then put them in the official extension directory - ${java.home}/jre/lib/ext.

Can anyone please explain me about the PHP/Java Bridge installation.
I already installed bridge in my system.

Can you please anyone help me on this.
Thanks in advance.

I am unfamiliar with the package you are trying to use but it looks like you need to give the full path to your class. That is java/lang/ClassNotFoundException for example for the Java Exception that is being thrown and probably something like me/mypackage/HelloWordl for the class you are trying to create.
