>          Issue Type: Bug
>    Affects Versions: 6.2.0.Final
>         Environment: Centos (Linux 2.6.32-431.5.1.el6.x86_64)

> But am using 6.2.0.Final
> Code is the basic use case:
> 		kServices = KieServices.Factory.get();
> 		releaseId = kServices.newReleaseId( "com.company", "rulesBrmsRepo", "LATEST" );
> 		kContainer = kServices.newKieContainer( releaseId );
> 		kScanner = kServices.newKieScanner( kContainer );
> //		// Start the KieScanner polling the maven repository every 5 mins
> 		kScanner.start( 300000L );
> Nothing particularly special about the occurrences, but once it happens, it stays broken.  Occurs randomly after a few hours of working without issue.
> It sometimes erroneously declares that:
>  Environment variable M2_HOME is not set
> though I suppose that has to do with using an internal Maven
> Another thing is it sometimes looks for the JAR in the plugins repo, which is only mentioned under pluginRepositories in settings.xml.  Why would it look for it there?
