so i have this model:

this content behavior
public class BugEventsListener {
private NodeService nodeService;
private BehaviourFilter policyFilter;
public void setPolicyFilter(BehaviourFilter policyFilter) {
this.policyFilter = policyFilter;
}
public void setNodeService(NodeService nodeService) {
this.nodeService = nodeService;
}
private PolicyComponent policyComponent;
public void setPolicyComponent(PolicyComponent policyComponent) {
this.policyComponent = policyComponent;
}
public void init() {
this.policyComponent.bindClassBehaviour(NodeServicePolicies.BeforeDeleteNodePolicy.QNAME,
BehaviorBugWebScript.TEST_ASPECT_1, new JavaBehaviour(this, "onDeleteChild",

}
public void onDeleteChild(final NodeRef nodeRef) {
System.out.println("TRYING TO DELETE: " + nodeRef);
policyFilter.disableBehaviour();
List<NodeRef> list = BehaviorBugWebScript.getTargetAssoc(nodeRef, BehaviorBugWebScript.TEST_ASSOC);
for (NodeRef node : list) {
nodeService.deleteNode(node);
}
}
}
and this is the script i running
public class BehaviorBugWebScript extends AbstractWebScript {
public static NodeService nodeService;

workaround is to run code in a new thread, but thats a bad solution:
Thread thread = new Thread() {
public void run() {
RunAsWork<Object> raw = new RunAsWork<Object>() {
public Object doWork() throws Exception {
List<NodeRef> list = BehaviorBugWebScript.getTargetAssoc(nodeRef, BehaviorBugWebScript.TEST_ASSOC);
for (NodeRef node : list) {
nodeService.deleteNode(node);
}
}
};
AuthenticationUtil.runAs(raw, AuthenticationUtil.getAdminUserName());
}
};
thread.start();
