Description

The GeoTools Quickstart example is forcing people to have JAI installed.

I think this happens because org.geotools.swing.tool.InfoTool imports some coverage module classes to use if a layer being queried contains a grid coverage or grid coverage reader.

It would be better to delay loading of these classes until they are required, perhaps by using reflection.

As an aside, the dependency graph generated in Netbeans doesn't include JAI for the Quickstart app !

Refactored InfoTool so that it no longer directly references any coverage module classes. It now works with helper classes to query layers. One of these, GridLayerHelper, handles grid coverage and grid coverage reader objects. The helpers are loaded lazily by InfoTool using rellection.

The Quickstart example and other apps using only vector feature data can now be run without JAI in the classpath.

Committed to trunk r34365 and 2.6.x r34366
