+jhat heap dump parsing tests:
+
+There are three hprof binary format dump files in this directory.
+These dumps were created by jmap and hprof profiler against a
+simple infinite looping Java program.
+
+1. minimal.bin - minimal dump that has nothing! - not even java.lang.Class!
+  - This was created by java -Xrunhprof:format=b,heap=sites MainClass. 
+
+2. jmap.bin - created by jmap -dump option
+
+3. hprof.bin - created by java -Xrunhprof:heap=all,format=b MainClass
+
+We can run jhat -parseonly true <dump-file> against these dumps.
