Bing maps does not satisfy tile request for zoom level 0

[The111]

The Bing maps API has a minimum zoom of 1.

However, most other tile sources in JMapViewer have a minimum zoom of 0. This should not be an issue, since Tile.loadPlaceholderFromCache can use the tile imagery data from zoom level 1 to populate the zoom level 0 tile. But the current TileController logic prevents this from working, since the loadPlaceholderFromCache method is only called for null tiles, but not after a server error.

Fixed in [o29245]. TileController now checks for server error and calls Tile.loadPlaceholderFromCache if needed.

Release zip updated.
