> When a bundle's Service-Component header contains explicit paths and wildcard
> paths, it is possible for an explicit descriptor entry to be parsed twice, if
> it is also matched by a wildcard entry. This results in an ERROR level log
> similar to that described in FELIX-2325. The use case which requires this mix
> of wildcard and non-wildcard entries is probably rare, but such is the
> situation with
> [https://github.com/Adobe-Consulting-Services/acs-aem-commons/issues/3241]
> In this situation, bnd is used to package the host bundle, and so the
> descriptors for the DS components contained within it are listed explicitly
> in the Service-Component header value generated by the bnd tool.
> Additionally, the project packages some optional component descriptors in a
> sidecar fragment bundle which cannot define its own Service-Component header.
> In order for SCR to load the optional components only when the fragment is
> attached, they must be listed by the host bundle's Service-Component header,
> but only implicitly by using a wildcard, so that their absence is not logged
> when the fragment is not attached.
