Something like.. ource.length == 0 ? 1 makes sure it turns a zero
length array into one. else it will never expand
public static byte[] expandArray(byte[] source) {
byte[] result = new byte[source.length == 0 ? 1 :
source.length * 2];
System.arraycopy(source, 0, result, 0, sourceLen.length);
return result;
}
