Harley,
When a Java 3D program starts there is much going on, threads spawning,
background getting painted, maybe garbage collection, ....
It is quite possible the rendering system is not able to render while
this is all taking place. This effect is worse in software rendering
environments.
Even so, it is possible for behaviors to
'take place' simply because they are time based. The door is going
to close even if a single frame is rendered.
You can:
1) make the door close based on some event so you can make it
happen when you want.
2) give a delay on the door close. The Alpha class allows you
to specify a delay time (before starting).
I hope this helps.
