Description Rüdiger Herrmann CLA 2010-05-16 08:12:23 EDT 
Using the CSS snippet leads to a NullPointerException
  background-image: gradient(
    linear, left, right,
    from( blue ),
    to( white )
  );

Variations thereof will probably also cause exceptions.

Stacktrace:
-------------
java.lang.NullPointerException

Comment 1 Ivan Furnadjiev CLA 2010-07-06 04:20:49 EDT 
CSS gradient parsing has been reworked to handle such invalid values and to throw IAE.
