             Summary: ClassPool cannot read generated classes
                 Key: JASSIST-263
                 URL: https://issues.jboss.org/browse/JASSIST-263
             Project: Javassist
          Issue Type: Bug
    Affects Versions: 3.20.0-GA
            Reporter: Paul Pogonyshev
            Assignee: Shigeru Chiba
         Attachments: JavassistBug.java

ClassPool.get() cannot retrieve classes that are in turn generated at runtime. For example, if I try to define at runtime two classes, one of which extends another, the base will not be found, even though it can be retrieved just fine from my class loader. See the attached example.

As far as I could trace it, the issue comes from ClassPoolTail.find() returning a null URL for the class. This is understandable, since class definition doesn't exist as a file --- it is generated at runtime. However, ClassPool.get() should still succeed for classes that have no URL, yet can be found through its ClassLoader.
