Alexander,
jmap doesn't support coredump (non-cooperative) access anymore. This
functionality moved to jhsdb.
As a long term, we should create two different set of tests - one for
cooperative mode (jmap, jstack, etc) and one for non-cooperative mode
(jhsdb).
Cooperative mode tests should resides alongside with other attach
related tests - i.e. in jdk/test/sun/tools
Non-cooperative mode (jhsdb) tests should be placed together with other
SA tests - in hotspot/test/serviceability/sa
