java.security.PrivilegedAction
Imports

Loads a class specified by name.

If no class loader is provided, first the thread context class loader is tried, and finally Hibernate Validator's own class loader.

Note

When loading classes provided by the user (such as XML-configured beans or constraint types), the user class loader passed to the configuration must be passed.

in some cases, the TCCL has been overridden so we need to pass it explicitly.

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.
