null pointer in inherited privileges and rules

Its the switch statement, maybe null?

for (RuleDefinition ruleDefinition : ruleEngine.getRuleDefinitions()) {
switch (ruleDefinition.getCheck().checkTypeEnum()) {
case attributeDefCreate:
case groupCreate:
case stemCreate:
switch (ruleDefinition.getThen().thenEnum()) {
case assignAttributeDefPrivilegeToAttributeDefId:
case assignGroupPrivilegeToGroupId:
case assignStemPrivilegeToStemId:

//see if the subject matches
