/**
 * Wraps an object with a proxy that sets Payara context around
 * every method call. This is useful for listeners, callbacks,
 * and other objects that run from another thread that may not have
 * Payara context initialized.
 *
 * This was create primarily to facilitate integration with Hazelcast,
 * which has listeners that do not capture Payara context.
 *
 * Example:
 * @Inject Contextualizer contextualizer;
 * @Inject MyListener myListener;
 *
 * // runs myListener.listen() method in a separate thread,
 * // with context captured from current thread
 * new Thread(contextualizer.contextualize(() -> myListener.listen(), Runnable.class));
