Refactoring pom files and fixing OSGi imports/exports
Hi,
Currently Stratos components do not properly import/export packages to/from
OSGi bundles. This might lead to unexpected behaviors in an OSGi runtime.
Also dependency versions in pom files are currently hard-coded which is
less maintainable. I've done a refactoring of all pom files to fix the
above issues. Following is a summary of changes done;
- Removed hard-coded maven dependency versions and moved everything to
parent pom
- Parameterized dependency versions with maven properties
- Added OSGi import ranges for external dependencies which are set from
parent pom as a maven property
- Added OSGi import version for Stratos internal dependencies as
project.version. This will ensure only intended component will always
- Upgraded commons-collections dependency to version 3.2.2 to mitigate the
security vulnerability as reported in [1]
While working on this I found several issues in the code base. I've
summarized the issues and fixes done below.
- Incorrect import of Arrays class in [2]
Changed the import to java.util.Arrays
- CloudController imports a private package of StratosCommon component [3]
Changed the import to CC's service holder class
- Incorrect dependency to org.wso2.carbon.identity.oauth.stub component at
[4,5] resulting unrunnable code at [6, 7]
This is because actual identity.oauth.stub bundle version packed into the
distribution is 4.2.3 and the dependency version defined in the Stratos
component is 4.2.0. Changed the dependency version to 4.2.3 and updated
code to be compatible with newer version.
- Metadata service webapp imports a private package of StratosCommon
component [8]
- Stratos rest endpoint webapp imports a private package of StratosManager
component [9]
Removed the private package import and used
PrivilegedCarbonContext->getOSGiService method in the Carbon kernel to
retrieve the ComponentStartUpSynchronizer OSGi service.
- Unnecessary Activator class in Autoscaler component [10].
Removed the class and reference in maven-bundle-plugin Bundle-Activator
directive.
- Embedded dependencies are not added as maven dependencies in the pom for
fabric8/kubernetes-api [11]
Added all relevant maven dependencies to the parent pom (with versions) and
sub-module (without versions).
Created a JIRA [12] to track these changes.
Following is a list of jars that were changed/upgraded as part of this
effort;
Old version -> New version
commons-collections-3.2.1.jar -> commons-collections-3.2.2.wso2v1.jar
commons-lang-2.6.jar -> commons-lang-2.6.0.wso2v1.jar

Hi Imesh,
Yes, I tested scaling, min check, fault detection features in ec2,
openstack, gce and Kubernetes iaas's. We have integration tests for
metadata service and group scaling features. According to Jenkins all tests
passed successfully.
Thanks.

Re: Refactoring pom files and fixing OSGi imports/exports

Great work Akila!
We might need to verify all the features after doing this modification.
Were you able to run any tests after doing this?
Thanks
