RFR: JDK-8186932: Fix accessibility issues in the java.management module

[Jonathan Gibbons]

Please review these relatively simple changes to fix accessibility 
issues in the java.management module.

JBS: https://bugs.openjdk.java.net/browse/JDK-8186932
Webrev: http://cr.openjdk.java.net/~jjg/8186932/webrev.00/
API: 
http://cr.openjdk.java.net/~jjg/8186932/api.00/java.management-summary.html


Most of the changes are to update tables to the de-facto standard 
"striped" pattern.

The one notable exception is MXBean:
http://cr.openjdk.java.net/~jjg/8186932/api.00/javax/management/MXBean.html
In this file, tables were used to display pairs of code samples 
side-by-side.
Although using "layout tables" would have been a possibility, a better 
solution is
to change to code samples to use  <div style="display:inline-block">.
