[java-dev] new MaxPatcher() not working in Max 5

Hello,

I'm having some problems with an mxj object in Max 5, which
is working fine in 4.6.3. Under Max 5, new patcher windows do not appear to be made correctly:

public void bang()
{
    MaxPatcher p  = new MaxPatcher(50,50,200,200);
    p.getWindow().setVisible(true);
    p.getWindow().setTitle("TEST PATCH");
}

Will give a window as expected under Max 4.6.3, but nothing under Max 5 -  p.getWindow().isVisible() remains false, even after calling p.getWindow().setVisible(true);

This is on a Powerbook G4, Mac OS X 10.4.11,  Max 5.0.1.

As a follow up, I tried similar code in a js object, which I believe should be:

function bang()
{
    p  = new Patcher(50, 50, 200, 200);
    p.wind.visible = 1;
    p.wind.title="TEST PATCH";  
    post(p.wind.visible);
}

but this gives no window in Max 5, or Max 4.6.3 or Max 4.5.6 (and the visible setting remains false) - am I missing something in the JavaScript version?
