Multiplicity 0..1 does not work - Exception in JavaContextFactory
-----------------------------------------------------------------
Key: TUSCANY-299
URL: http://issues.apache.org/jira/browse/TUSCANY-299
Project: Tuscany
Type: Bug
Components: Java SCA POJO Container
Versions: M1
Reporter: Jean-Sebastien Delfino
Fix For: M1
In your component do the following:
@Reference(required=false)
public void setGreetingSuffix(GreetingPortionProvider greetingSuffix) {
this.greetingSuffix = greetingSuffix;
}
and do not wire that reference. This should work, greetingSuffix should just be
null. Instead you'll get the following exception:
java.lang.IndexOutOfBoundsException: Index: 0, Size: 0
