Hi,

we are facing some troubles updating a 3.6 based RCP application to the
3.7 codebase.

All except one of the included dependent plugins are updating fine, just
the org.eclipse.equinox.event bundle gives us some headache.

The updated application does not start, the logfile says this:

-----------CUT-----------
!MESSAGE [SCR] Found components with duplicated names! Details:
Component1 : Component[
name = org.eclipse.equinox.event
activate = activate
deactivate = deactivate
modified =
configuration-policy = optional
factory = null
autoenable = true
immediate = false
implementation = org.eclipse.equinox.internal.event.EventComponent
state = Unsatisfied
properties =
serviceFactory = false
serviceInterface = [org.osgi.service.event.EventAdmin]
references = null
located in bundle = org.eclipse.equinox.event_1.2.100.v20110502
[366]
]
Component2: Component[
name = org.eclipse.equinox.event
activate = activate
deactivate = deactivate
modified =
configuration-policy = optional
factory = null
autoenable = true
immediate = false
implementation = org.eclipse.equinox.internal.event.EventComponent
state = Unsatisfied
properties =
serviceFactory = false
serviceInterface = [org.osgi.service.event.EventAdmin]
references = null
located in bundle = org.eclipse.equinox.event_1.2.0.v20100503 [76]
]
-----------CUT-----------

I just fail to understand why
org.eclipse.equinox.event_1.2.100.v20110502 doesn't just get precendence
over the older org.eclipse.equinox.event_1.2.0.v20100503, the relevant
part of feature.xml looks the same for both 3.6 and 3.7 versions of the
application:

-----------CUT-----------
<plugin
id="org.eclipse.equinox.event"
download-size="0"
install-size="0"
version="0.0.0"
unpack="false"/>
-----------CUT-----------

Any hints what could cause the trouble in this case?

Thanks in advance!

Udo
