PR #2872 added support to consider additional methods as constructors for the purposes of UWF_FIELD_NOT_INITIALIZED_IN_CONSTRUCTOR; however the approach implemented there does not seem to be compatible with JUnit 3. In JUnit 3 the initialization method is called setUp and does not have any annotations.

As an alternative, I suggest adding setUp as a whitelisted method name here, or if that is too loose it could be conditional on the method being a descendant of junit.framework.TestCase.
