Affected tests:
test/manual/images/animated/ImageLoadingManualTest_rotating_earth.java

Error occures while trying to show rotating_earth.gif (in attachment). A simple Java FX application for viewing GIFs (for Netbeans) is also in attachment (rotating_earth.gif already exists in project). All you have to do is change path1 variable in ImageViewer.java:
private String path1 = "rotating_earth.gif";

This is a regression. Picture is shown when using Java FX 2.0.1 (with defects though, see RT-19238), and is not shown with Java FX 2.1.1 b03 and 2.1.0 b22

Note: this is not a duplicate of RT-19238. That issue is about animated GIF is not rendered properly, this bug is about not being able to show it at all.
