Nested classes read from ClassMemberValue cannot be loaded ---------------------------------------------------------- Key: JASSIST-209 URL: https://issues.jboss.org/browse/JASSIST-209 Project: Javassist Issue Type: Bug Affects Versions: 3.18.0-GA Reporter: Ben Romberg Assignee: Shigeru Chiba I'm trying to upgrade Javassist in my project from version 3.16.1 to 3.18.0. I'm using the ClassMemberValue to load the (String) class-name of an annotation value, in order to load the class with Javassist using ClassPool.get(...). In 3.16.1, the returned class-name String for nested classes contained the $-sign, as in package.ParentClass$NestedClass, which didn't have any issues using the String with ClassPool.get(...). In 3.18.0 however, the returned class-name String for nested classes changed to a pure dot-notation, as in package.ParentClass.NestedClass, which cannot be used with ClassPool.get(...) anymore, as Javassist tries to load the class-file from package/ParentClass/NestedClass.class instead of package/ParentClass$NestedClass.class. I don't see any way to work around the issue without hacking into internal API, as the class-name String is the only way to get the annotation value. As this is a generic class (and not always a nested class), I also cannot simply replace the last dot with a $-sign.
