Sub Tasks

Description
The set of available standard JMX queries (javax.management.QueryExp) has expanded slightly over time.  The original set was defined in version 1.0 of the JMX API, way back in 2000.  It remained unchanged through to 1.2, which was included with Java SE 5.0.

In Java SE 6 we added Query.isInstanceOf, which is documented with a @since tag.

In version 2.0 of the JMX API, we're including the ability to use dotted attribute expression like A.b.c, with the same meaning as for monitors (see javax.management.monitor).  We need to document clearly that this capability is not available if you are connected to a remote agent that has an earlier version of the JMX API.

Fixed while adding JMX.getSpecificationVersion.

EVALUATION

This should at least be mentioned in Query.attr and in AttributeValueExp.getAttribute.  We should probably also add something to the introductory text for the Query class that mentions the possible interoperation problems for dotted attribute expressions and for isInstanceOf.
