[OpenJDK 2D-Dev] [9] Review request for 8047066: Test test/sun/awt/image/bug8038000.java fails with ClassCastException

[anton nashatyrev]

Hello,
    could you please review the following fix:
fix: http://cr.openjdk.java.net/~anashaty/8047066/9/webrev.00/ 
<http://cr.openjdk.java.net/%7Eanashaty/8047066/9/webrev.00/>
bug: https://bugs.openjdk.java.net/browse/JDK-8047066

    we just need to check whether the Raser sample model is the 
ComponentSampleModel, else fall back to a slower method.

Thanks!
Anton.
