Raymond Feng resolved TUSCANY-1309.
-----------------------------------
Resolution: Invalid
If the reference/service under the <component> doesn't match what are declared
(or introspected) on the componentType, we produce a warning. In this case, the
variable is not a SCA reference and no injection happens. So it's default to
null and NPE is a user error.
> NPE if SCDL uses component reference that is not defined consistently in the
> implementation

> Key: TUSCANY-1309
> URL: https://issues.apache.org/jira/browse/TUSCANY-1309
> Project: Tuscany
> Issue Type: Bug
> Components: Java SCA Assembly Model
> Affects Versions: Java-SCA-0.90
> Environment: Win XP
> Reporter: Simon Laws
> Assignee: Jean-Sebastien Delfino
> Priority: Minor
> Fix For: Java-SCA-Next

>
> For example,
> public class AlertsServiceImpl {
> private RSSCheckerService rssChecker;
>
> private AlertsSourcesService alertsSources;
> @Reference
> public void setRssChecker(RSSCheckerService rssChecker) {
> this.rssChecker = rssChecker;
> }
>
> // missing explicit reference defintion for alertsSources.
> ...
> }
> Then the SCDL...
> <component name="AlertsServiceComponent">
> <implementation.java
> class="org.apache.tuscany.sca.samples.aggregator.AlertsServiceImpl" />
> <reference name="rssChecker" target="RSSCheckerComponent"/>
> <reference name="alertsSources"
> target="AlertsSourcesServiceComponent"/>
> </component>
> Results in NPE
