Component descriptor reference elements are not ordered
-------------------------------------------------------
Key: FELIX-2275
URL: https://issues.apache.org/jira/browse/FELIX-2275
Project: Felix
Issue Type: Bug
Components: Maven SCR Plugin
Affects Versions: maven-scr-plugin-1.4.2
Reporter: Stephen Flynn
We use SCR annotations (1.2.0) and the SCR Maven Plug-in (1.4.2) to generate DS
1.1 component descriptors. All works well except for one issue - we cannot find
a way to control the order of <reference/> elements in the generated descriptor
through the @Reference annotation. A cursory glance suggests that <reference/>
elements generated by the plug-in are not ordered in any way.
The order of binding is significant. From the 4.2 Compendium spec....
*112.5.7 Binding Services*
"When binding services, the references are processed in the order in which
they are specified in the component description. That is, target services from
the first specified reference are bound before services from the next specified
reference."
We can work around this by manually creating descriptors but this is
sub-optimal for obvious reasons.
This appears to be caused by capturing references in a HashMap in the class
SCRDescriptorGenerator.java. Should probably be a LinkedHashMap instead.
