Yes, that's also right. The bindex tool generated the repository.xml
and added the missing info, as shown in this xml fragment:
<capability name='bundle'>
<p n='manifestversion' v='1'/>
<p n='presentationname' v='Framework Data Source'/>
<p n='symbolicname' v='Framework Data Source'/>
<p n='version' t='version' v='1.1.0'/>
</capability>
Unfortunately, what is happening is the bundle that is failing with the
NPE is also described in the same way:
<capability name='bundle'>
<p n='manifestversion' v='1'/>
<p n='presentationname' v='Framework Plugin'/>
<p n='symbolicname' v='Framework Plugin'/>
<p n='version' t='version' v='1.1.1'/>
</capability>
What I can determine by reading through the repository.xml is that a
couple of "requires" for the second bundle were either missing or
deprecated. However, I'm not certain if this is the source of the
problem. Also, could you confirm if packages referenced from the
classpath through the system bundle are "safely" visible to OBR and
resolved successfully? These packages would of course appear in a
"require" tag as well yet they are not exported by any bundle.
OBR converts every locally installed bundle into a Resource, including
the system bundle. Make sure that all of your locally installed bundles
have symbolic names. If they do, then we will have to track it
down...perhaps you can send me a URL to your repo and the steps to
reproduce the exception (or some sort of tar ball off line).

Yes, that's correct. Here is a portion of the manifest:
Bundle-Name: Framework Data Source
Bundle-Description: Data Source Layer.
Bundle-Version: 1.1
Bundle-Activator: com....framework.ds.Activator
Bundle-ClassPath: .
Export-Package: ...
Import-Package: ...
I was just hoping that the exception from OBR will be able describe
what
dependency failed to resolve so that the appropriate action can be
taken. I will also try to insert some code to make this happen as
well.
What is the scenario that is happening when you do see the exception?
It possible, as Steven suggested, that this could be related to whether
the metadata is coming from XML or the manifest. For example, if you
have a bundle installed locally without a bundle symbolic name, then
when this is converted into a resource, it won't have a symbolic name,
which could cause the NPE.
How did you generate the XML? Did you use bindex? Maybe it
automatically adds the symbolic name.
Just some thoughts.

Hmmm. I wonder how this worked:

name and the one shown below is given by default?
I don't recall doing it that way, but anything is possible...it has
been a long time since I worked on OBR. The last time I saw this bug,
though, I am fairly certain it was because there was no symbolic name.
I will try to take a closer look at it and see if I can see what is
going on.

Looking at the output from obr info, the repository.xml generated by
bindex shows that the Bundle-Name has been used as a substitute
when the
Bundle-SymbolicName descriptor is missing from the manifest. Hence
my
guess is that the obr deploy command fails with an NPE only when
dependencies are not satisfied.
I don't think so. OBR requires a bundle symbolic name, because this
plus version is a unique identifier.

It looks like either the symbolic name or the version are nil. I
