-------------------------------------------------------------------
After analysing we found that there are 2 following methods which needs to be
addressed/ checked. We analysed and tried/ checked all possible scenarios which
might leads to NullPointerException. Details are as follows .
[getConditionDef(String conditionName)
|https://github.com/apache/ranger/blob/master/agents-common/src/main/java/org/apache/ranger/plugin/policyevaluator/RangerDefaultPolicyItemEvaluator.java#L284]
test case1: for variable conditionName = null
test case2: for variable conditionName = not null
[newConditionEvaluator(String
className)|https://github.com/apache/ranger/blob/master/agents-common/src/main/java/org/apache/ranger/plugin/policyevaluator/RangerDefaultPolicyItemEvaluator.java#L308]
test case1: for variable className = null and result = null
test case2: for variable className = not null
Since we are not able to reproduce/ come-up with a scenario which leads to
NullPointerException, we conclude no action required on this task.
