RE: [Jython-dev] applet problemsHi. Sorry for the too quick and not precise
remark:

jythonc applets compiled wrt the system classes of jdk 1.3  do not work under
IE and I think netscape 4.- either.

Reason: jdk 1.3 introduces new comp. hierarchy related events,
doing is job jythonc introduces explicit references to their handling procs in
the applet (proxy):

  ...
    public void processHierarchyBoundsEvent(java.awt.event.HierarchyEvent arg0)
{
        super.processHierarchyBoundsEvent(arg0);
    }

    public void processHierarchyEvent(java.awt.event.HierarchyEvent arg0) {
        super.processHierarchyEvent(arg0);
    }
 ...

java 1.1-like runtimes will fail to link the applet with their system classes
=> so the applet will not work.
Nothing to do directly with class-format or compiler issues.

In some sense this broad and sometime spurious references to the actual methods
of the base class break
some of the nice features of java related to robustness wrt to class changes.
But that's the way jythonc actually works.

PS: sorry for the too imprecise -> too technical move.
