Description Tomas Hurka 2013-08-08 08:59:34 UTC

Currently JavaClass.getInstances() starts search for instances at the beginning of instance dump segment. It is possible to remember offset of the first instance and start search from that offset. This will improve performance of JavaClass.getInstances() on big heap dumps for classes with instances, which are close to each other and for all classes with one instance.
