Loading the "Moon" background takes about 30 seconds, which is more than 10x
longer than any other background.
To reproduce this, run lg3d and bring up the backgroung manager. Select
"Layered" images. If you select the "Moon" image – which is a compsite image of
a star field, the earth, the moon, and a space station – and press "OK", LG
will take about 30-40 seconds to load the image, during which time no
interaction is possible.
This could be either a Java 3D problem or a LG3D problem. I don't know whether
it is a regression. I have attached the logfile as well a thread dump. The
thread dump shows a lot of time spent in a color space conversion function.
