When using the KieScanner as indicated in the guide, if the kContainer is initalized using a ReleaseIdImpl that idicate
as version "RELEASE", the KieScanner do not find changes in the repository if we indicate as RELEASE a previous version of the repository.
IN CODE:

ReleaseIdImpl releaseId = new ReleaseIdImpl("blabla", "blabla", "RELEASE");
KieServices ks = KieServices.Factory.get();
kContainer = ks.newKieContainer(releaseId);
kieScanner = ks.newKieScanner(kContainer);
kieScanner.start(5000L);

For example if we change the maven-metadata.xml/maven-metadata-local.xml

FROM
<metadata>
<groupId>com.noemalife.dmcs.rules</groupId>
<artifactId>maven-validation-rules</artifactId>
<versioning>
<release>0.2</release>
<versions>
<version>0.1</version>
<version>0.2</version>
</versions>
<lastUpdated></lastUpdated>
</versioning>
</metadata>

TO
<metadata>
<groupId>com.noemalife.dmcs.rules</groupId>
<artifactId>maven-validation-rules</artifactId>
<versioning>
<release>0.1</release>
<versions>
<version>0.1</version>
<version>0.2</version>
</versions>
<lastUpdated></lastUpdated>
</versioning>
</metadata>

The kieScanner do not find changes; I have to restart the AS to be able to load the correct RELEASE version.
(The kieScanner behaves and updates correctly if I change the release version from 0.1 to 0.2 )
