[statics] allowing static initializers in interfaces?

[Maurizio Cimadamore]

Hi,
now that the work on allowing static members in nested declarations [1] 
is wrapping up, I'm wondering if we could add treatment for one more 
case: static initializers in interfaces. This seems a case where the 
static compiler is already inserting static blocks (to initialize any 
static fields an interface might declare), but where the JLS is 
currently forbidding interfaces from having an explicit static 
initializer block in the source code. This make e.g. initialization of 
fields which might throw exceptions (e.g. method handles) not possible 
inside interfaces. While I realize this is a corner case, I thought it 
would still be worth asking the question :-)

Cheers
Maurizio
