/**
* Part of the test suite for the WebView's Java Bridge. This class tests the
* general use of arrays.
*
* 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.JavaBridgeArrayTest \
