> One usecase of JmxTool is to allow user to query all existing objects and
> attributes, such that the developer can quickly lookup the right object name
> and attribute name in the output. Indeed, existing API of JmxTool allows user
> to do this when object-name is not specified in argument.
> However, current implementation of JmxTool doesn't support this operation due
> to the way it is implemented. This is partly due to the fact that some JMX
> object, such as java.lang:type=MemoryPool, doesn't have value for all its
> attributes.
> The patch submitted here will fix the problem.
