ImageIO plugin fails to import *.img files

Symptom

The net.refractions.udig.catalog.imageio plugin fails to import ERDAS IMAGINE (*.img) files.

Test

Import --> Data --> Files --> Select any valid *.img file --> Select Finish --> Nothing happens

Cause

The following test fails in the static constructor of net.refractions.udig.catalog.imageio.ImageServiceExtension

static{

    // the other tests....

    // HFA
    driverCode="HFA";    
    if(GDALUtilities.isDriverAvailable(driverCode))
    {
        factories.put(driverCode, new DTEDFormatFactory());
        fileExtensions.put(driverCode,Arrays.asList("dt0","dt1", "dt2"));
    }
		
}

which is wrong. It should be Arrays.asList("img") , not Arrays.asList("dt0","dt1", "dt2"). This is probably an uncompleted cut-n-paste operation from the DTED test to the HFA test (the former test is currently equal to the latter). After correcting this error, the ImageIO plugin imports (*.img) files without any problems.
