Another issue is that dynamically created classes are not found in the classpools.
Dynamic proxies are not found at all:

Neither are the javassist ProxyFactory proxies, since they just define the class in the classloader with no way to find them from the pools:

In AOP what we did was to write the class bytes to the in memory vfs location from the aop classpools, so that when trying to look up the CtClass later there is a resource path for the class bytes:
URL outputURL = new URL(tempURL.toString() + "/" + classFileName);
//Write the classfile to the temporary url
synchronized (tmplock)
{
if (trace) logger.trace(this + " " + pool + ".toClass() myloader:" + myloader + " writing bytes to " + tempURL);
ByteArrayOutputStream byteout = new ByteArrayOutputStream();
BufferedOutputStream out = new BufferedOutputStream(byteout);
out.write(cc.toBytecode());
out.flush();
out.close();
byte[] classBytes = byteout.toByteArray();
MemoryContextFactory factory = MemoryContextFactory.getInstance();
factory.putFile(outputURL, classBytes);
Going to check with Chiba, but I'll see if I can modify javassist to allow ProxyFactory and ProxyFactoryHelper to accept an interface like
interface ByteRecorder{
void writeBytes(String classname, byte[]) throws IOException
}
