        Description

        Attached test program show an endless loop in the native code of sun.java2d.loops.ScaledBlit in EDT. The problem is a consequence of a very large value in a AffineTransform. It occur with all Java 6, Java 7 and Java 8 versions on different Windows systems. Other OS we have not tested.
