Please add more Assert.assertArrayEquals methods like:

assertArrayEquals(boolean[] expecteds, boolean[] actuals)
assertArrayEquals(float[] expecteds, float[] actuals)
assertArrayEquals(double[] expecteds, double[] actuals)

assertArrayEquals(String message, boolean[] expecteds, boolean[] actuals)
assertArrayEquals(String message, float[] expecteds, float[] actuals)
assertArrayEquals(String message, double[] expecteds, double[] actuals)

I see no cause because this is not implemented in Assert see at http://www.junit.org/apidocs/org/junit/Assert.html for details.
