> NullPointerException if a property is not configured
> ----------------------------------------------------
>
> Key: TUSCANY-220
> URL: http://issues.apache.org/jira/browse/TUSCANY-220
> Project: Tuscany
> Type: Bug
> Components: Java SCA POJO Container
> Reporter: Jean-Sebastien Delfino
> Assignee: Jim Marino
>
> By default the application developer is not required to configure all the
> properties of a component. If a property is not configured, the runtime
> throws a NullPointerException. Ths is not correct, no exception should be
> thrown.
> To reproduce the problem, just comment out the property configuration element
> in helloworldmc/sca.module, as follows:
> <component name="HelloWorldServiceComponent">
> <implementation.java
> class="org.apache.tuscany.samples.helloworldmc.HelloWorldServiceComponentImpl"/>
> <references>
> <v:greetingPrefix>GreetingPrefixComponent</v:greetingPrefix>
> <v:greetingSuffix>GreetingSuffixComponent</v:greetingSuffix>
> </references>
> <properties>
> <!--
> <v:greetingMiddle>SCA</v:greetingMiddle>
> -->
> </properties>
> </component>
> Here's the exception you'll get when you run the HelloWorldClient.
> Exception in thread "main" java.lang.NullPointerException
