# String#split with a "dot"

String#split with a dot "." does return an empty array:

    String packages[] = "com.airhacks".split(".");
    assertThat(packages.length, is(0));


The split method parameter is a regular expression, and 
"dot" is Any character (may or may not match line terminators)


Escaping the dot solves the "problem":    


    String packages[] = "com.airhacks".split("\\.");
    assertThat(packages.length, is(2));
