/**
 * Part of the test suite for the Java Bridge. This class tests that we correctly convert
 * JavaScript arrays to Java arrays when passing them to the methods of injected Java objects.
 *
 * The conversions should follow
 * http://jdk6.java.net/plugin2/liveconnect/#JS_JAVA_CONVERSIONS. Places in
 * which the implementation differs from the spec are marked with
 * LIVECONNECT_COMPLIANCE.
 * FIXME: Consider making our implementation more compliant, if it will not
 * break backwards-compatibility. See b/4408210.
