Issue1047347

If you have a Java class signature that doesn't have a
constructor with no
arguments like:

DoSomeStuff(int foo)
DoSomeStuff(float foo)

and you DON'T have:

DoSomeStuff()

Then when you try to subclass DoSomeStuff, you get a
compile error because it
generates code to handle the non-existant
"DoSomeStuff()" case.

If StarInterpolator is a subclass of
RotationInterpolator, this causes errors
like :

Compiling .java to .class...
    [snip]
1  ./jpywork/Star.java:243: cannot resolve symbol
symbol  : constructor RotationInterpolator ()
location: class javax.media.j3d.RotationInterpolator
            super();
            ^

super() doesn't exist because RotationInterpolator()
doesn't exist.

If you go into the generated code and delete the
following code

         StarInterpolator() {
            super();
            __initProxy__(new Object[] {});
        }

then it compiles just fine.

Interesting, there's a no-argument prototype, but it's not
public:

[17:27:20]# javap javax.media.j3d.TransformGroup 
Compiled from "TransformGroup.java"
public class javax.media.j3d.TransformGroup extends
javax.media.j3d.Group{
    public static final int ALLOW_TRANSFORM_READ;
    public static final int ALLOW_TRANSFORM_WRITE;
    public javax.media.j3d.TransformGroup();
    public
javax.media.j3d.TransformGroup(javax.media.j3d.Transform3D);
    void createRetained();
    public void setTransform(javax.media.j3d.Transform3D);
    public void getTransform(javax.media.j3d.Transform3D);
    public javax.media.j3d.Node cloneNode(boolean);
    void duplicateAttributes(javax.media.j3d.Node,boolean);
}

I'm not a java programmer so I don't understand why, except
the no-argument version is not useful.  I set
python.security.respectJavaAccessibility = false and got the
following  traceback:

I HAVE A FIX!

In proxies.py make the following change:

*** 346,363 ****
--- 346,365 ----
      def addConstructors(self, c):
          for constructor in c.getDeclaredConstructors():
              access = constructor.modifiers
              if isPrivate(access):
                  continue
              if isNative(access):
                  access = access & ~NATIVE
              if isProtected(access):
                  access = access & ~PROTECTED | PUBLIC
+             if not access:
+                 continue
              parameters = tuple(constructor.parameterTypes)
              throws = constructor.exceptionTypes
              self.jconstructors.append( (access,
parameters, throws) )
  
      def callSuperMethod(self, name, supername, access,
ret, sig, throws=[]):
          if self.issuperproxy:
              return
          self.supermethods[supername] = supername
          args = [typeName(ret)]

This makes it ignore constructors for which you have no access.
