#277 ModelMBeanInfoSupport addRequiredFields bug

[Anonymous]

method addRequiredFields skip field "persistPolicy"
because use a lowercase name "persistpolicy".
In the class "DescriptorSupport" always use
the "persistPolicy" field name as stated in JMX
specification.
It's not possible to persist MBean with this version
(3.0.2).
