One change has an issue but the others seem fine. You really need reviewers from each component area though.
Thanks.

The return value from `CFDictionaryContainsKey` is a Boolean and is assigned to this variable. So I think these changes are the wrong way round. Keep this as a Boolean but convert the return value to jboolean:
return beforeAdd ? JNI_TRUE : JNI_FALSE;
