@panchenko Thanks! The fix looks good. Could you change the unit test like that (TestSpatialReference.java):

package com.esri.core.geometry;

import junit.framework.TestCase;
import org.junit.Test;

public class TestSpatialReference extends TestCase {
    @Test
    public void testEquals() {
        final SpatialReference a = SpatialReference.create("GEOGCS[\"GCS_WGS_1984\",DATUM[\"D_WGS_1984\",SPHEROID[\"WGS_1984\",6378137.0,298.257223563]],PRIMEM[\"Greenwich\",0.0],UNIT[\"Degree\",0.0174532925199433]]");
        final SpatialReference b = SpatialReference.create("PROJCS[\"WGS_1984_Web_Mercator_Auxiliary_Sphere\",GEOGCS[\"GCS_WGS_1984\",DATUM[\"D_WGS_1984\",SPHEROID[\"WGS_1984\",6378137.0,298.257223563]],PRIMEM[\"Greenwich\",0.0],UNIT[\"Degree\",0.0174532925199433]],PROJECTION[\"Mercator_Auxiliary_Sphere\"],PARAMETER[\"False_Easting\",0.0],PARAMETER[\"False_Northing\",0.0],PARAMETER[\"Central_Meridian\",0.0],PARAMETER[\"Standard_Parallel_1\",0.0],PARAMETER[\"Auxiliary_Sphere_Type\",0.0],UNIT[\"Meter\",1.0]]");
        final SpatialReference c = SpatialReference.create("GEOGCS[\"GCS_WGS_1984\",DATUM[\"D_WGS_1984\",SPHEROID[\"WGS_1984\",6378137.0,298.257223563]],PRIMEM[\"Greenwich\",0.0],UNIT[\"Degree\",0.0174532925199433]]");
        assertTrue(a.equals(a));
        assertTrue(b.equals(b));
        assertTrue(a.equals(c));
        assertTrue(!a.equals(b));
        assertTrue(!b.equals(a));
    }
}

@stolstov Why a combination of juni3/junit4 styles? it looks confusing.

[stolstov]

@panchenko I only can say that it works like that too :). The naming convention should stay but feel free to fix this to a better style.

@stolstov I've updated this test
