Kingdom: API Abuse

An API is a contract between a caller and a callee. The most common forms of API abuse are caused by the caller failing to honor its end of this contract. For example, if a program fails to call chdir() after calling chroot(), it violates the contract that specifies how to change the active root directory in a secure fashion. Another good example of library abuse is expecting the callee to return trustworthy DNS information to the caller. In this case, the caller abuses the callee API by making certain assumptions about its behavior (that the return value can be used for authentication purposes). One can also violate the caller-callee contract from the other side. For example, if a coder subclasses SecureRandom and returns a non-random value, the contract is violated.

Often Misused: sun.misc.Unsafe

Abstract
The application uses functionality from sun.misc.Unsafe. All functionality in this class is inherently unsafe to use and can only be accessed via reflection.
Explanation
The sun.misc.Unsafe class is for performing unsafe, low-level operations and is not intended for use by developers.
The Unsafe class can only be obtained by trusted code and is normally obtained through reflection, because it can be used for corrupting the system or manually allocating heap memory that if not properly handled could have detrimental affects on the system. It is imperative that all functionality around sun.misc.Unsafe must be carefully reviewed and tested to be absent of fault.
