John Ross resolved ARIES-902.
-----------------------------
Resolution: Fixed
Fixed in http://svn.apache.org/viewvc?view=revision&revision=1371183.
Knowing when to retain or remove constituent relationships between subsystems
and bundles can be tricky. For example, the subsystem being uninstalled may
have a reference to a bundle that's a dependency provisioned to (i.e. is a
constituent of) another subsystem. If the reference count is zero, the
constituent relationship between the bundle and the other subsystem should be
removed. Note that the subsystem being uninstalled may be the "provisioned to"
subsystem if it accepts dependencies. The reference count cannot always be
relied upon, however. In the case of an unscoped subsystem being uninstalled
that shares a bundle with another unscoped subsystem, the reference count will
not be zero but the constituent relationship should be removed nevertheless.
The approach taken in this patch attempts to cover all possibilities by always
removing the constituent relationship between the subsystem being acted upon
(i.e. the subsystem being uninstalled) and the bundle. There is no harm done if
the relationship does not actually exist. Then, if the resource is
uninstallable (i.e. reference count equals zero), the constituent relationship
between the "provisioned to" subsystem and the bundle is removed. There is no
harm done if the "provisioned to" subsystem turns out to be the same subsystem
as the one being acted upon.

> When uninstalling a subsystem, the reference count is not being checked

> subsystem and bundle resources. If the reference count is not equal to zero,
> the constituent relationships should not be removed. For example, the bundle

> resource of the "provisioned to" subsystem.
