This dispatcher analyzes the stack frames to detect if a particular call should be authorized.

Authorized classes are registered when creating the ByteBuddy proxies.

It should only be used when the Security Manager is enabled.

public Class<?>[] run()

Implements java.security.PrivilegedAction.run.

Doc from java.security.PrivilegedAction.run.

Performs the computation. This method will be called by AccessController.doPrivileged after enabling privileges.

Returns:Class<?>[]

a class-dependent value that may represent the results of the computation. Each class that implements PrivilegedAction should document what (if anything) this value represents.
