Grzegorz Grzybek resolved ARIES-1858.
-------------------------------------
Resolution: Fixed
> Make typed property placeholders compatible with older Camel versions
> ---------------------------------------------------------------------
>
> Key: ARIES-1858
> URL: https://issues.apache.org/jira/browse/ARIES-1858
> Project: Aries
> Issue Type: Improvement
> Components: Blueprint
> Affects Versions: blueprint-core-1.10.0
> Reporter: Grzegorz Grzybek
> Assignee: Grzegorz Grzybek
> Priority: Major
> Fix For: blueprint-core-1.10.1
>
>
> ARIES-1298 changed the runtime class of bean registered from
> {{{http://aries.apache.org/blueprint/xmlns/blueprint-ext/v1.x.0}property-placeholder}}
> and
> {{{http://aries.apache.org/blueprint/xmlns/blueprint-cm/v1.x.0}property-placeholder}}.
> This is definitely not caught by semver plugin.
> {{camel-blueprint}} (see CAMEL-12570) added support for this new runtime
> class - it was needed because Camel explicitly casts and uses reflection on
> old {{org.apache.aries.blueprint.ext.AbstractPropertyPlaceholder}} class,
> while blueprint-core 1.10.0 registers placeholder class that extends
> {{org.apache.aries.blueprint.ext.AbstractPropertyPlaceholderExt}} - and these
> two are not related.
> The problem is that when user will try to upgrade to e.g., Karaf with
> blueprint-core 1.10.0 *without upgrading Camel*, Camel blueprint will stop
> detecting blueprint property resolvers.
