Konrad Windszus commented on SLING-11728:
-----------------------------------------
For me the [JLS
13.5.2|https://docs.oracle.com/javase/specs/jls/se11/html/jls-13.html#jls-13.5]
is clear in that regard:
"Changes to the interface hierarchy cause errors in the same way that changes
to the class hierarchy do, as described in §13.4.4. In particular, changes that
result in any previous superinterface of a class no longer being a
superinterface can break compatibility with pre-existing binaries, resulting in
a VerifyError."
The "can break" points at the fact that this does not necessarily have to be
the case. But I wouldn't rely on it, if it works for a certain edge case. So
IMHO we should rather follow baselining recommendation....
> Remove bi-directional dependencies between Engine and Servlets Resolver

> Key: SLING-11728
> URL: https://issues.apache.org/jira/browse/SLING-11728
> Project: Sling
> Issue Type: Improvement
> Components: API, Engine, Servlets
> Affects Versions: Engine 2.12.0
> Reporter: Oliver Lietz
> Assignee: Oliver Lietz
> Priority: Major
> Time Spent: 1.5h
> Remaining Estimate: 0h
>
> *Situation*
> * bundle {{org.apache.sling.engine}} requires a {{ServletResolver}} which is
> provided by bundle {{org.apache.sling.servlets.resolver}}
> * bundle {{org.apache.sling.servlets.resolver}} depends on
> {{org.apache.sling.engine.servlets}} API
> The bi-directional dependencies between Engine and Servlets Resolver prevent
> the creation of meaningful and light deployment units (testing, features).
> *Options*
> # Merge {{org.apache.sling.engine}} and
> {{org.apache.sling.servlets.resolver}} into a single entity (bundle)
> # Move {{org.apache.sling.engine.servlets.ErrorHandler}} into Sling API
> (package {{org.apache.sling.api.servlets}}) and adjust usage in Servlets
> Resolver
> # Keep as is – leading to bigger, less manageable deployment units
