>          Issue Type: Bug
>          Components: Core

> While trying to upgrade from 2.15.0 to 2.16.0, we discovered some of our unit tests were failing. On further investigation, we realized that the new {{JndiManager.isJndiEnabled()}} method, on first call, causes initialization of all static members of {{{}JndiManager{}}}, including a call to {{{}NetUtils.getLocalIps{}}}. In at least one of our unit test frameworks, this generates a NullPointerException. 
> Could some of the {{permanentAllowed}} lists initialization be deferred to avoid this issue?
