I just tried VisualVM (the screenshot I linked) and it is extremely easy to use.
But I'm not sure anymore that it will help because if I filter the heap for class names containing "dspace" (this includes the package name), all those classes are small (< 0.1 % size). The classes taking up most memory are char[] and byte[], which of course doesn't tell us much. When I dig down and view instances, they look like metadata values, so I assume they come from Solr. There may simply be too much data there in Solr and Solr is trying to keep it in memory (which is its purpose).
