Comment 2 Jan Stola 2014-04-22 09:01:57 UTC 
Thank you for catching this. It is a consequence of the fix of issue 241098. The exception shows that "selectorList" property is present in given CSS Rule, it has "selectors" sub-property but its type is array of Strings. Unfortunately, I have tested this on the latest version of Chrome (where the type of "selectors" is array of JSONObjects) and Embedded Browser from JDK 7 (where "selectorList" is not present). I overlooked that there is another version of the protocol (used by Embedded Browser in JDK 8).

For the sake of completeness, there are the mentioned changes in Chrome:
Introduction of "selectorList" (with an array of Strings):
http://src.chromium.org/viewvc/blink/trunk/Source/devtools/Inspector-1.1.json?r1=129469&r2=129470&
Replacement of the array of Strings by an array of Selectors (JSONObjects):
http://src.chromium.org/viewvc/blink/trunk/Source/devtools/protocol.json?r1=159732&r2=159733&
