SDG is using bundlor to generate the MANIFEST.MF file.I already fixed
the MANIFEST and the spring data neo4j bundle can now be resolved.
But when the spring application context is loaded, the class
"org.springframework.data.graph.neo4j.config.Neo4jConfiguration"
cannot be found during bean postprocessing and aspectj magic (see
stacktrace below).
The class is available and exported. I checked that with clhas and
clexport on the Virgo console. Does maybe the kernel space of Virgo
has to to know the spring data neo4j bundle, because this aspectj
"enhancements" are performed there?
Best regards
