Please review JDK-8144914 "Eagerly lookup browser JS object class in BrowserJSObjectLinker" at <http://cr.openjdk.java.net/~attila/8144914/webrev.jdk9.jdk> for <https://bugs.openjdk.java.net/browse/JDK-8144914>
(Note that line 96 replaces “return null” for “return inv” – the distinction only makes sense in presence of non-standard operations, which we currently don’t have, but even so that’s pedantically more correct.) Thanks, Attila.
