It looks like the glue layer produces new compile warnings due to errorprone:

../../android_webview/glue/java/src/com/android/webview/chromium/ContentSettingsAdapter.java:614: warning: [MissingOverride] setDisabledActionModeMenuItems implements method in WebSettings; expected @Override
    public void setDisabledActionModeMenuItems(int menuItems) {
                ^
    (see http://errorprone.info/bugpattern/MissingOverride)
  Did you mean '@Override public void setDisabledActionModeMenuItems(int menuItems) {'?
../../android_webview/glue/java/src/com/android/webview/chromium/ContentSettingsAdapter.java:618: warning: [MissingOverride] getDisabledActionModeMenuItems implements method in WebSettings; expected @Override
    public int getDisabledActionModeMenuItems() {
               ^
    (see http://errorprone.info/bugpattern/MissingOverride)
  Did you mean '@Override public int getDisabledActionModeMenuItems() {'?
../../android_webview/glue/java/src/com/android/webview/chromium/WebViewChromiumFactoryProvider.java:690: warning: [MissingOverride] getTokenBindingService implements method in WebViewFactoryProvider; expected @Override
    public TokenBindingService getTokenBindingService() {
                               ^
    (see http://errorprone.info/bugpattern/MissingOverride)
  Did you mean '@Override public TokenBindingService getTokenBindingService() {'?
../../android_webview/glue/java/src/com/android/webview/chromium/WebViewContentsClientAdapter.java:300: warning: [MissingOverride] isRedirect implements method in WebResourceRequest; expected @Override
        public boolean isRedirect() {
                       ^
    (see http://errorprone.info/bugpattern/MissingOverride)
  Did you mean '@Override public boolean isRedirect() {'?


... (and many more) ...

I think we can just add the appropriate @Override annotations.
