[jira] [Created] (KARAF-6865) Feature dependency is failing
randomly in feature resolver
shriram created KARAF-6865:
------------------------------
Summary: Feature dependency is failing randomly in feature resolver
Key: KARAF-6865
URL: https://issues.apache.org/jira/browse/KARAF-6865
Project: Karaf
Issue Type: Bug
Components: karaf
Affects Versions: 4.1.4
Reporter: shriram
I am writing an application which has a dependency with other feature.
- Feature A
- Feature B
Feature A has a dependency with Feature B so i declared it in
<features xmlns="http://karaf.apache.org/xmlns/features/v1.0.0">
<repository>mvn:com.eclipsesource.jaxrs/features/4.3/xml/features</repository>
<feature name="FeatureA" version="1.0.0" install="auto">
<feature>FeatureB</feature>
</feature>
Most of the times both the both the KAR's are properly deployed. Once in a while i am facing an issue that Feature B is only installed and listed in list command in KARAF console. But Feature A is there(there in deploy folder).
I have gone through the KARAF source code and found the logic that
If feature A comes first it waits in **DelayedDeployerThread** with 2 milliseconds time. Once Feature B is installed it sets the variable cancel to true so comes out of the loop and FeatureA proceeds for installation.

and finally lands in the error

Expected behaviour is it should wait until the feature B completes and starts the installation. Same thing happens
in the success case

Not sure why the failures doesn't waits in the loop and continues for feature A installation also the time difference is 1 millisecond.
We are using maven plugin to generate the feature file and there is an documentation for an attribute "**prerequisite**" which mandates the feature B to complete(started/activated) before feature A
Any help would be appreciated.
I tried it with prerequisites attribute in the feature xml still issue persists.
