When Image object created via:

Image img = new Image(MyApp.class.getResource("flower.png").toExternalForm(), true);

It can not be used for ImagePattern because of runtime exception:

java.lang.IllegalArgumentException: Image must be non-null

But if one changed "true" parameter to "false" then ImagePattern created well.

I attached source code. It generate exception, but if line with ImagePattern commented, app works fine.

PS. It can has same origin - if I try create Image with
new Image("filename", isBackgroundLoading)

ImagePattern creation fails no matter, which parameter was used.
