JDK-5096280 - NEWHPROF: manual incorrectly specifies array object field
Description
hprof binary format requires that HPROF_GC_OBJ_ARRAY_DUMP records should refer to class ID of array's class (instead of the class ID of the element type -  jmap heap dumper uses element class ID.). That is, if there's an array of Foo, this field points to the class "Foo[]", not to the class "Foo".  The element type is "Foo". (refer to 5096280 as well).
