The proper use of white space makes a major contribution to code readability.
This rule raises an issue when there is not a space character after the beginning and before the end of each comment (<!-- ...
-->), directive (<%@ ... %>), and expression (<% ... %>).
<!--Do the thing--> <!-- Noncompliant; missing space at beginning and end of text--> <%@page import="java.io.*,java.util.*" %> <!-- Noncompliant; missing space at beginning --> <% String title = "My Page";%> <!-- Noncompliant; missing space at end -->
<!-- Do the thing --> <%@ page import="java.io.*,java.util.*" %> <% String title = "My Page"; %>
