Detailed description:

Problem reported by aris:

Hello. Using latest version of GWT 1.5 from SVN (#2866), and latest
version from SVN of gwt-google-apis (#304), with the next code the
application stops running in the .addOverlay(m) line. It doesn’t shows
any exception or error (tried on HostedBrowser, on IE7 and FF2 with
FireBug), but sending comments to the console before and after the
line .addOverlay(m), it shows the comment before that line, but not
the later comment.

MarkerOptions mo = new MarkerOptions();
Icon ic = new Icon("http://192.168.3.148:8080/Images/Map/
mapMarker.png");
mo.setIcon(ic);

Marker m = new Marker(new LatLng(p.latitude,p.longitude), mo);
mapWidget.addOverlay(m);

Workaround if you have one:

Using a Marker() without a MarketOptions()... works ok, but with the
common icon used by markers

...

I made some changes to the sample and found that removing the line

icon.setIconAnchor(new Point(6, 20));

replicates the problem. It stops running without any error.
I just added a .setIconAnchor() to my application, and now it works.

The attached JS sample replicates the problem outside of GWT.

Even though this seems to be a problem with the underlying Maps API, it is 
pretty simple to work around in the API.  The problem also exists in the 
Icon(String url) constructor.

Another manual workaround is to create the Icon using new Icon(DEFAULT_ICON) 
and then
change what you want to change.

In investigating this problem I discovered two mis-named methods in Icon that I 
want
to correct before it gets into widespread use:

 setTransparentImageUrl --> setTransparentImageURL
 getTransparentImageUrl --> getTransparentImageURL

and the Size.equals() method was broken (used the Object.equals method).
