/**
 * Part of the test suite for the WebView's 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.
 *
 * To run this test ...
 *  adb shell am instrument -w -e class com.android.webviewtests.JavaBridgeArrayCoercionTest \
