             Project: Drools
          Issue Type: Bug
          Components: core engine
    Affects Versions: 6.2.0.Final
         Environment: RHEL 6.5, JDK 1.7.0_71, Wildfly 8.2, Sonatype Nexus 2.11.3-0

We're facing a lot of issues with permgen OOM errors while using the KIE CI implementation to get the rules during runtime from a Nexus host.

A jmap analysis shows that 414MB of dead permgen is produced by org/eclipse/sisu/space/CloningClassSpace$CloningClassLoader at 0x00000007ef60b6a0

With a dependency tree analysis it's shown, that only kie CI uses the sisu classes:

The most current version of the sisu implementation is 0.3.1 while kie-ci is using 0.0.0.M5. Maybe this is related to a bug in sisu with this old version.

Is it possible to include a newer version of sisu with ki-ci?
