public abstract class J2DoPrivHelper
extends java.lang.Object

Helper class to obtain the Privilege(Exception)Action object to perform Java 2 doPrivilege security sensitive function call in the following methods:

AccessibleObject.setAccessible
Class.forName
Class.getClassLoader
Class.getDeclaredField
Class.getDeclaredFields
Class.getDeclaredMethod
Class.getDeclaredMethods
Class.getProtectionDomain
Class.getResource
Class.newInstance
ClassLoader.getParent
ClassLoader.getResource
ClassLoader.getResources
ClassLoader.getSystemClassLoader
File.deleteOnExit
File.delete
File.exists
File.getAbsoluteFile
File.getAbsolutePath
File.getCanonicalPath
File.listFiles
File.length
File.isDirectory
File.mkdirs
File.renameTo
File.toURL
FileInputStream new
FileOutputStream new
System.getProperties
InetAddress.getByName
MultiClassLoader new
ServerSocket new
Socket new
Socket.accept
System.getProperty
Thread.getContextClassLoader
Thread.setContextClassLoader
Thread new
TemporaryClassLoader new
URL.openStream
URLConnection.getContent
ZipFile new
AnnotatedElement.getAnnotations
AnnotatedElement.getDeclaredAnnotations
AnnotatedElement.isAnnotationPresent
jakarta.validation.Validator.validate
jakarta.validation.Validation.buildDefaultValidatorFactory

If these methods are used, the following sample usage patterns should be followed to ensure proper privilege is granted:

 1) No security risk method call. E.g.

    private static final String SEP = J2DoPrivHelper.getLineSeparator();

 2) Methods with no exception thrown. PrivilegedAction is returned from
    J2DoPrivHelper.*Action(). E.g.

    ClassLoader loader = AccessController.doPrivileged(
                             J2DoPrivHelper.getClassLoaderAction(clazz));

    ClassLoader loader = (ClassLoader) (System.getSecurityManager() == null)
                         ? clazz.getClassLoader()
                         : AccessController.doPrivileged(
                             J2DoPrivHelper.getClassLoaderAction(clazz));
 3) Methods with exception thrown. PrivilegedExceptionAction is returned
    from J2DoPrivHelper.*Action(). E.g.

    try {
      method = AccessController.doPrivileged(
        J2DoPrivHelper.getDeclaredMethodAction(clazz, name, parameterType));
    } catch (PrivilegedActionException pae) {
      throw (NoSuchMethodException) pae.getException();
    }

    try {
      method = (System.getSecurityManager() == null)
        ? clazz.getDeclaredMethod(name,parameterType)
        : AccessController.doPrivileged(
            J2DoPrivHelper.getDeclaredMethodAction(
              clazz, name, parameterType));
    } catch (PrivilegedActionException pae) {
        throw (NoSuchMethodException) pae.getException()
    }
