JDK-8057919 Class.getSimpleName() should work for non-JLS compliant class names

[Jochen Theodorou]

Hi all,

this mail is refering to 
http://mail.openjdk.java.net/pipermail/core-libs-dev/2015-April/032733.html 
and JDK-8057919

In a groovy program

def cl = { -> '' }
assert cl.class.anonymousClass == false

the open block {->''} is compiled into an inner class. We had problems 
with this in the past, because for several reasons we did not follow the 
JLS naming conventions here. The change in JDK-8057919 was supposed to 
make things better, but the change also means that our open block class 
will now have an empty simple name. At the same time reflection tells me 
the class is not an anonymous class.

If I see this right, then regardless of if we set the attributes right 
or not, reflection and getSimpleName have a differing understanding 
about the nature of that class. I consider that a bug. They should have 
a common understanding about what a anonymous inner class is, since 
getSimpleName is supposed to return an empty string for that case.

plus... it would be really really nice if someone could tell me how a 
non-anonymous class in a method has to look like with javap, so that I 
can know from there if it is no anonymous and finally fix he flags for 
Groovy's class generation.

Because javap and the asm lib really don't help much with getting inner 
classes and their flags right.

bye jochen
