a KieProject from an ogsi bundle

It seems that we have 2 issues :
1) Even if drools-osgi-integration (fragment bundle) is deployed and classes added to the
classloader of drools-compiler, the following error is reported :
2013-06-21 09:42:34,649 | ERROR | ExtenderThread-2 | ClasspathKieProject |
builder.impl.ClasspathKieProject 93 | 80 - org.drools.compiler - 6.0.0.20130621-0836 |
Unable to build index of kmodule.xml url=bundle://212.1:1/META-INF/kmodule.xml
2) During the creation of kcontainer, something happens as the Map of GAVs is equal to
zero, reason why we get a NPE
