9 Checkstyle configuration that checks the sun coding conventions from:
10
11 - the Java Language Specification at
12 http://java.sun.com/docs/books/jls/second_edition/html/index.html
13
14 - the Sun Code Conventions at http://java.sun.com/docs/codeconv/
15
16 - the Javadoc guidelines at
17 http://java.sun.com/j2se/javadoc/writingdoccomments/index.html
18
19 - the JDK Api documentation http://java.sun.com/j2se/docs/api/index.html
20
21 - some best practices
22
23 Checkstyle is very configurable. Be sure to read the documentation at
24 http://checkstyle.sf.net (or in your downloaded distribution).
25
26 Most Checks are configurable, be sure to consult the documentation.
27
28 To completely disable a check, just comment it out or delete it from the file.
29
30 Finally, it is worth reading the documentation.

36 The default severity setting in checkstyle is 'error', so some
37 of the rules below are configured to change the severity to
38 'warning'. Over time, these 'warning' settings should be
39 removed as more of the ONOS source code is modified to
40 follow the recommended rules.
