Sanne Grinovero commented on ISPN-6252:
---------------------------------------

What do you mean by "manipulate it" and/or change the slot? Can this be done at runtime, on a per-deployment base?

We can not patch the static definition of existing modules, that would break other applications.

An alternative: as far as I remember the only module which needs both worlds in the same picture is the Infinispan DirectoryProvider for Hibernate Search: that's meant to link to the Hibernate Search instance included in WildFly/EAP, and therefore should be using its Lucene module (rather than the Infinispan/Lucene module).

Considering that Infinispan Query has its own very specific needs on how it sets up the Directory, I'm wondering if we should rather not share the DirectoryProvider module for both Query and Hibernate Search. If you make the Infinispan DirectoryProvider compatible with Hibernate Search / WildFly only, and give Infinispan Query a similar alternative we should be good and the two projects would be able to have completely independent Lucene versions.

> Apache Lucene 5.5 is released now, and is "drop-in compatible" with versions 5.3 and 5.4 so you don't have to wait for an Hibernate Search release.
> It's also being the last one for the 5.x series before 6, so I expect that we'll see some more micro releases for maintenance but essentially that this will be some form of long term commitment.
