MethodTooLargeException when creating the proxy for the Port type

[papegaaij]

When trying to use the virtual box sdk on Java 21, we get the following exception:

Exception in thread "Thread-5" jdk.internal.org.objectweb.asm.MethodTooLargeException: Method too large: jdk/proxy2/$Proxy89.<clinit> ()V

The service endpoint interface it tries to generate the proxy for is very large. It has 1832 methods. However, this used to work fine with Java 17. Note, we transformed the virtualbox sdk jar to make it compatible with Jakarta EE.
