- Subject: Java/parse.y: Type clashes on the default action
In a rule such as
foo: bar {} baz;
you implicitly say
foo: bar {} baz { $$ = $1; };
Hence foo and bar must have the same type. It was not the case for
the rules below. I have also slightly adjusted the style of the
surrounding actions so that they have the same style.

from Akim Demaille <akim@epita.fr>
* parse.y (class_declaration, interface_declaration): Make sure
all their rules have an action, in order to avoid meaningless `$$
= $1' and their type clashes.
