Issue : https://bugs.openjdk.java.net/browse/JDK-8129215
Webrev: http://cr.openjdk.java.net/~jbachorik/8129215/webrev.00

The JMX Introspector will try to use the JavaBeans introspector whenever 
possible, delegating the requests for the property getter/setter 
methods. However, when the JavaBeans introspector is not available 
(modules) the JMX Introspector falls back to its own simple, reflection 
based, algorithm.

The simple algorithm does not enforce the rule of property names 
starting with a lower-case letter. This might lead to situations when 
the simple introspector provides the getter method for an attribute the 
JavaBeans introspector would not (eg. 'Attribute' attribute)

This patch changes the simple introspector behaviour to conform to the 
one of the JavaBeans introspector. Also, it makes the simple 
introspector called only when the JavaBeans introspector is not 
available - and not when the JavaBeans introspector fails to resolve a 
property getter.
