WebView doesn't render html input elements

Wed Jun 24 16:12:01 UTC 2015

Hi Alexander,

Yes, the issue exists indeed. I've filed it as: JDK-8129800 
<https://bugs.openjdk.java.net/browse/JDK-8129800> [WebView] controls not showing up initially on 
Linux. However, I don't reproduce it with your test but with a slightly different one.

Anyway, thanks for reporting it.

Regards,
Anton.
