I think what is happening is that post obfuscation your class has been
named 'a/Print' but the string reference in the joinpoint is still
'hmil.Print'. The AspectJ runtime actually tries to resolve the class
before returning the name (i.e. getDeclaringTypeName() calls
getDeclaringType().getName()). The error handling will return a
ClassNotFoundException.class when hmil.Print cannot be resolved.
Can you tell the obfuscator to also modify string references to types? You
might like it to avoid resolving in this case and just return the string,
but currently you can't do that. It hasn't been made configurable because
I think it is unusual that it can't resolve the class it is in... The
string form of the declaringType isn't even stored in the signature object
for you to access via reflection, the ctor converts it to a class reference
straight away...
