   I found another example. That's easier to understand.

   This goes in onWindowReady

   JavascriptClassDefinition oneClassDef = new JavascriptClassDefinition().name("one").attributes(JavascriptClassAttributes.NO_AUTOMATIC_PROTOTYPE);
   			JavascriptClass oneClass = oneClassDef.bake();
   			JavascriptObject oneObject = context.makeObject(oneClass);
   			globalObject.setProperty("one", oneObject, 0);
   
   			JavascriptClassDefinition twoClassDef = new JavascriptClassDefinition().name("two").parentClass(oneClass).attributes(JavascriptClassAttributes.NO_AUTOMATIC_PROTOTYPE);
   			JavascriptClass twoClass = twoClassDef.bake();
   			JavascriptObject twoObject = context.makeObject(twoClass);
   			oneObject.setProperty("two", twoObject, 0);
   
   			JavascriptClassDefinition threeClassDef = new JavascriptClassDefinition().name("three").parentClass(twoClass).attributes(JavascriptClassAttributes.NO_AUTOMATIC_PROTOTYPE);
   			threeClassDef.onCallAsFunction(new JavascriptObjectFunction() {
   
   				@Override
   				public JavascriptValue callAsJavascriptFunction(JavascriptContext context, JavascriptObject function, JavascriptObject thisObject, JavascriptValue[] arguments) throws JavascriptInteropException {
   					if (true) {
   						JavascriptValue string = context.makeString("[{\"x\":-156.5,\"z\":265.5,\"type\":5},{\"x\":-158.5,\"z\":265.5,\"type\":5},{\"x\":-152.5,\"z\":267.5,\"type\":5},{\"x\":-160.5,\"z\":267.5,\"type\":5},{\"x\":-148.5,\"z\":267.5,\"type\":5},{\"x\":-150.5,\"z\":267.5,\"type\":5},{\"x\":-160.5,\"z\":265.5,\"type\":5},{\"x\":-154.5,\"z\":267.5,\"type\":5},{\"x\":-154.5,\"z\":265.5,\"type\":5},{\"x\":-152.5,\"z\":265.5,\"type\":5},{\"x\":-150.5,\"z\":265.5,\"type\":5},{\"x\":-158.5,\"z\":267.5,\"type\":5},{\"x\":-171.31021364279692,\"z\":240.2766290600617,\"type\":0},{\"x\":-162.5,\"z\":265.5,\"type\":5},{\"x\":-156.5,\"z\":267.5,\"type\":5},{\"x\":-148.5,\"z\":265.5,\"type\":5},{\"x\":-155.44999998807907,\"z\":272.44999998807907,\"type\":3},{\"x\":-162.5,\"z\":267.5,\"type\":5},{\"x\":-242.5,\"z\":242.5,\"type\":4}]");
   						//string.contextUnlocking();
   						return string;
   					}
   					return context.makeBoolean(false);
   				}
   			});
   			JavascriptClass threeClass = threeClassDef.bake();
   			JavascriptObject threeObject = context.makeObject(threeClass);
   			twoObject.setProperty("three", threeObject, 0);

   this exaggerates the memory leak, calls one.two.three a crap ton and task manager shows memory increasing by about 150MB per second. Looking at VisualVM shows that all objects java side are being correctly garbage collected. There must be something natively that is not releasing some memory?

    function update() {
       for (let index = 0; index < 2500; index++) {
           // @ts-ignore
           let f = one.two.three("");
           // @ts-ignore
           let f1 = one.two.three("");
           // @ts-ignore
           let f2 = one.two.three("");
         }
     }
   
    function animationFrame() {
       update();
       requestAnimationFrame(animationFrame);
     }
     requestAnimationFrame(animationFrame);
