JDBCFeatureSourceTest cannot work with DB2 Spatial Extender

Reason 1) no rounding

JDBCFeatureSourceTest>>testBoundary

assertEquals(0d, bounds.getMinX());
assertEquals(0d, bounds.getMinY());
assertEquals(2d, bounds.getMaxX());
assertEquals(2d, bounds.getMaxY());

should check with rounding, the following would work:

assertEquals(0d, new Double(Math.round(bounds.getMinX())));
assertEquals(0d, new Double(Math.round(bounds.getMinY())));
assertEquals(2d, new Double(Math.round(bounds.getMaxX())));
assertEquals(2d, new Double(Math.round(bounds.getMaxY())));

The same holds true for

JDBCFeatureSourceTest>>testBoundsWithQuery

assertEquals(1d, new Double(Math.round(bounds.getMinX())));
assertEquals(1d, new Double(Math.round(bounds.getMinY())));
assertEquals(1d, new Double(Math.round(bounds.getMaxX())));
assertEquals(1d, new Double(Math.round(bounds.getMaxY())));

Reason 2) CRS check in

JDBCFeatureSourceTest>>testSchema
JDBCFeatureSourceTest>>testBoundary
JDBCFeatureSourceTest>>testBoundaryWithQuery

The line

assertEquals(CRS.decode("EPSG:4326"), bounds.getCoordinateReferenceSystem());

is hard stuff. DB2 Spatial Extender has his WGS 84 CRS , but it is not equal as implemented in geotools.

A good idea would be to introduce a protected method

protected boolean areCRSEqual(crs1, csr2) {
return crs1.equals(crs2);
}

und use it

assertTrue(areCRSEqual(CRS.decode("EPSG:4326"), bounds.getCoordinateReferenceSystem()));

This would give me the possiblity to do my own special equal check in my Test class.
