Hi, can you explain please why this check is done, what else can the proxy
be, apart from null or ThreadLocalProxy ? Thanks
> JAX-RS @Context fields throw NPE in OSGI hot deployed filters
> -------------------------------------------------------------
>
> Key: CXF-7309
> URL: https://issues.apache.org/jira/browse/CXF-7309
> Project: CXF
> Issue Type: Bug
> Components: JAX-RS
> Affects Versions: 3.0.12, 3.1.10
> Reporter: Ezequiel Rosas Garcia
>
> Hello.
> This happens with a PreMatching filter that is loaded from OSGI.
> I found that when the filter OSGI bundle is hot deployed, all other already
> running bundles using it would start throwing NPE when trying to access the
> injected fields inside the filter (like CXF-7248)
> This seems to happen due to other bundles retaining their ThreadLocal
> references in their own AbstractResourceInfo#getSetterProxyMap() while the
> OSGI Proxy starts redirecting to a new filter object which has new different
> ThreadLocal references as soon as it is used for the first time after hot re
> deployment.
> Test:
