resolveUsingClassback to summary
public ResolvedType resolveUsingClass(Class<?> clazz)

Resolve a type using the specified class. Normal resolution in a reflection world uses Class.forName() via the classloader (attached to this world) in order to find a named type then builds a reference type and a reference type delegate based on that. For some classes generated at runtime (e.g. proxy or lambda representation) the forName() call will not work. In those situations we should just use the clazz we have. Should the whole thing switch from using forName() to using the clazz objects? Possibly but that introduces a lot of change and we don't have a lot of test coverage for this scenario (reflection world). What we are doing right now is that this can optionally be used if the regular resolution scheme did not work. Although AspectJ is *not* multi threaded or re-entrant, Spring doesn't always respect that. There might be an issue here if two attempts are made to resolve the same thing at the same time via this method.

Parameters
clazz:Class<?>

the class to use as the delegate for the resolved type

Doc from org.aspectj.bridge.IMessageHandler.handleMessage.

Handle message, by reporting and/or throwing an AbortException.

Parameters
message:IMessage

the IMessage to handle - never null

Returns:boolean

true if this message was handled by this handler

Exceptions
AbortException:
depending on handler logic.
