Sure there is. JavaFX ships a WebView component (literally called that) which runs on every platform including embedded. It's WebKit-based. You don't like WebKit but at every point in the web's history there were some browsers with more features or fewer bugs than others. If you're writing web apps then you're meant to run on more than one rendering engine.

At any rate there's also JCEF, again for JVM apps.

It embeds Chromium.
