------- Comment #2 from mmitchel at gcc dot gnu dot org 2007-01-09 02:47 -------
Of course, in C++, A would have a default constructor, since no constructor was
explicitly declared. But, is a Java type not supposed to have a constructor in
this case? If not, why not? That seems fundamentally at odds with C++; it
would be more C++-ful, if we want to prevent construction, to have a declared
constructor -- but make it both undefined and private?

------- Comment #3 from tromey at gcc dot gnu dot org 2007-01-09 18:46 -------
We already only support 'extern "Java"' classes where the body of the
class is written in Java and compiled with gcj. The reason for this is
that a Java class has a lot of required metadata which g++ does not know
how to generate.
So, I think the only truly supported way to make an extern "Java" class is
via gcjh. (Well, plus a couple of special cases in libjava.)
Given this, I think it would be fine to just have a constructor-less
extern "Java" class be a fatal error. The Java compiler will always emit
a default constructor, and hence gcjh-generated headers will always be
correct.

Hi Tom, we still have this rather old P2 (ans also 30294), was wondering
whether you would be interested...

Yeah, for both this and for PR 30294, I think we can just reject some
constructs very early. I don't think it makes sense to declare variables,
fields, or functions with "java" types that are not pointers.
The only question here, I think, is whether libgcj uses this construct.
Maybe there could still be a bug for 30293 though.
