The problem is caused by not supporting the PEGA framework.
PRAppLoader is not allowing addURL to be called.
Can you check if there is a related option?

It looks like you need to modify the code below.

    // JarProfilerPluginClassInjector.java
    public <T> Class<? extends T> injectClass(ClassLoader classLoader, String className) {
        try {
            if (bootstrapCore.isBootstrapPackage(className)) {
                return bootstrapCore.loadClass(className);
            }
            if (classLoader == null) {
                return bootstrapClassLoaderHandler.injectClass(null, className);
            } else if (classLoader instanceof URLClassLoader) {
                final URLClassLoader urlClassLoader = (URLClassLoader) classLoader;
                return urlClassLoaderHandler.injectClass(urlClassLoader, className);
            } else {
                return plainClassLoaderHandler.injectClass(classLoader, className);
            }
        } catch (Throwable e) {
            // fixed for LinkageError
            logger.warn("Failed to load plugin class {} with classLoader {}", className, classLoader, e);
            throw new PinpointException("Failed to load plugin class "   className   " with classLoader "   classLoader, e);
        }
    }

i have builded this pinpoint-profiler-3.0.1-SNAPSHOT.jar seems new it is newer version can i deploy the same , Also i just modified code, still getting same /NULL values, can you please give some guidlines to get my pegapp url statistics
