Inline adoc files when they are included exactly once. Also fix language tags because this inlining gives us better information on what language the code is written in.

=== Noncompliant code example
|
|
|
|
[source,java]
|
|
----
|
|
static final Pattern p = Pattern.compile("^$", Pattern.MULTILINE); // Noncompliant
|
|
|
|
// Alternatively
|
|
static final Pattern p = Pattern.compile("(?m)^$"); // Noncompliant
|
|
|
|
|
|
boolean containsEmptyLines(String str) {
|
|
return p.matcher(str).find();
|
|
}
|
|
|
|
// ...
|
|
System.out.println(containsEmptyLines("a\n\nb")); // correctly prints 'true'
|
|
System.out.println(containsEmptyLines("")); // incorrectly prints 'false'
