for the method ofClassFile image

we generate a unit test for it image

If binaryRepresentation has length 7, then the last accessible index is 6, so the binaryRepresentation[7] & 255 will throw an ArrayOutOfBoundsException when the length is exactly 7.

In Java, array indexes go from 0 to array.length - 1

Although I think that EvoSuite should generate a test saying that calling ofClassFile(a) with a an array of size 7, is expected to throw an exception.
