| Test if a VM is attachable. If it's not attachable,
an AttachNotSupportedException will be thrown. For example,
1.4.2 or 5.0 VM are not attachable. There are cases that
we can't determine if a VM is attachable or not and this method
will just return.
This method uses the jvmstat counter to determine if a VM
is attachable. If the target VM does not have a jvmstat
share memory buffer, this method returns.
exception: AttachNotSupportedException - if it's not attachable |
