<Swing Dev> <Swind Dev> [7u6] Review request for 6836089: Swing HTML parser can't properly decode codepoints outside the Unicode Plane 0 into a surrogate pair

[Vladislav Karnaukhov]

Hello Pavel,

please find new webrev here: 
http://cr.openjdk.java.net/~vkarnauk/6836089/webrev.02/

I've fixed code style mistakes and re-wrote test, it now conforms to 
Swing test rules. I also run this test with jtreg to check if it works 
(it does).

Regards,
- Vlad
