Sanne Grinovero commented on ISPN-3311:
---------------------------------------

Hi Galder,
the {{lucene-v3}} vs. {{lucene}} split in Maven is only a source-level split. The assembled jar contains compiled classes from both v3 and v4 modules: we had to use a Maven hack to support both versions of Lucene and still be backwards compatible in terms of module definition. Nothing too magic, we just merge the two built modules and then generate the OSGi stuff as last step.

If this just affects the entries stored via the Lucene Directory then it's definitely less critical: indexes can be rebuilt from the data; if it's a {{LifecycleCallbacks}} issue I guess that could even be compensated for by registering them explicitly?
