Returns the GC information about the most recent GC. This method returns a GcInfo. If no GC information is available, null is returned. The collector-specific attributes, if any, can be obtained via the CompositeData interface.

MBeanServer access: The mapped type of GcInfo is CompositeData with attributes specified in GcInfo.

Returns:a GcInfo object representing the most GC information; or null if no GC information available.
