Description of problem:
Uberfire is no longer a droolsjbpm core component since 6.2.x, please put it into jboss-integration-platform-bom, since other projects like DV, FSW's project also depends on uberfire.
Eg: in droolsjbpm-build-bootstrap:
<version.org.uberfire>0.4.2.Beta1</version.org.uberfire>
<guvnor.version>${drools.version}</guvnor.version>
<uberfire.extensions.version>${drools.version}</uberfire.extensions.version>

This should be put into community bom.
