ami tabak updated JASSIST-171:
------------------------------
Attachment: root-cause.jpg
Root cause is that the delimiter of the inner class Mapper$Context is not $ but rather a
"." (dot)e.g. Mapper.Context.
Looking at hadoops source code the inner class is defined as
"...
public class Mapper<KEYIN, VALUEIN, KEYOUT, VALUEOUT> {
public class Context ..{
}
..."
Calling SignatureAttribute$MethodSignature.toString results in
RuntimeException: bad descriptor
