Create reproducer test case for issue #874

[ptziegler]

Consider the following situation: The SimRel 2023-12 repository contains FasterXML Jackson bundles with version 2.16.0, with the exception of one bundle that is still in 2.15.3.

In order to ensure that all those bundles have the same version, the one in 2.15.3 is also contributed via Maven Central (imitated by a local directory) in 2.16.0.

Trying to resolve this target definition fails with: No repository found containing:
osgi.bundle,
com.fasterxml.jackson.module.jackson-module-jaxb-annotations,
2.16.0

Meaning PDE knows that there is a newer version available, it just doesn't know where to find it...
Note that one can work around this problem by explicitly adding the missing bundle to the IU location.

Cannot invoke "org.eclipse.equinox.internal.p2.repository.Transport.download(java.net.URI, java.io.OutputStream, org.eclipse.core.runtime.IProgressMonitor)" because the return value of "org.eclipse.equinox.internal.p2.repository.helpers.AbstractRepositoryManager.getTransport()" is null

Of course the test doesn't work during the Jenkins run... 😠

it could be you need an additional test requirement for the ECF transport.

Not sure why GitHub decided to close this one but in the end, I don't think this test would've gone anywhere...

Several test are disabled during the Jenkins build via PDETestCase.assumeRunningInStandaloneEclipseSDK() for similar reasons. So I assume it's simply not possible to connect to a "real" repository during the test.
The pull request is continued via #962

@ptziegler this can happen if if you push a commit that is even with master (e.g. you did not push any changes).

Actually it should be possible, maybe we should rethink that but of course it could slow down the build a bit.
