What steps will reproduce the problem?
1. executing
List<HGValueLink> all = getAll(graphDB, type(String.class));
on a HGDB instance with 65.536 Long-Atoms and 1.000.000 String Atoms from
outside of a transaction.
What is the expected output? What do you see instead?
Expected: Getting all the String-Labeld Edge Atoms from the database.
Got instead:
$ cat logs/65536_1000000.geoff-hypergraphdb-readWholeGraph.stdout
checkpoint kbytes:0
checkpoint minutes:0
