How to scan for a particular annotation of java classes loaded at runtime as a bytocode?

1. If a java class loaded at runtime as a bytecode (e.g. via ASM library or other mechanism), is it on a classpath of java? I don't see it.


2. How to scan all annotations of classes loaded this way, if it's not on the java classpath?

p.s. I use google reflections and a custom classloader of a 3-rd party library.
