---------------------------------
Summary: LoadDistributorFeature not comaptible with JAX-RS
subresources
Key: CXF-9052
URL: https://issues.apache.org/jira/browse/CXF-9052
Project: CXF
Issue Type: Bug
Components: JAX-RS
Affects Versions: 3.6.4, 4.0.5, 3.5.9
Reporter: Vadim Beilin
LoadDistributorTargetSelector seems to be confused by subresources.
I'm attaching a test that demonstrates it below.
When no clustering features or FailoverFeature is applied, the client tries to
invoke 'http://localhost:1234/sub/name', as expected. -- `noClustering` and
`failover` pass.
When LoadDistributorFeature is applied, the request is to
'http://localhost:1234/name' (path segment contributed by the root resource is
lost) -- `loadDistributor` fails.
