      public class CertPathValidatorException
      extends GeneralSecurityException

  An exception indicating one of a variety of problems encountered when validating a certification path.

  A `CertPathValidatorException` provides support for wrapping exceptions. The `getCause` method returns the throwable, if any, that caused this exception to be thrown.

  A `CertPathValidatorException` may also include the certification path that was being validated when the exception was thrown, the index of the certificate in the certification path that caused the exception to be thrown, and the reason that caused the failure. Use the `getCertPath`, `getIndex`, and `getReason` methods to retrieve this information.

  Concurrent Access

  Unless otherwise specified, the methods defined in this class are not thread-safe. Multiple threads that need to access a single object concurrently should synchronize amongst themselves and provide the necessary locking. Multiple threads each manipulating separate objects need not synchronize.

- - ### Constructor Detail

    - #### CertPathValidatorException

          public CertPathValidatorException()

      Creates a `CertPathValidatorException` with no detail message.

    - #### CertPathValidatorException

          public CertPathValidatorException(String msg)

      Creates a `CertPathValidatorException` with the given detail message. A detail message is a `String` that describes this particular exception.
      Parameters:
        `msg` - the detail message

    - #### CertPathValidatorException

          public CertPathValidatorException(Throwable cause)

      Creates a `CertPathValidatorException` that wraps the specified throwable. This allows any exception to be converted into a `CertPathValidatorException`, while retaining information about the wrapped exception, which may be useful for debugging. The detail message is set to (`cause==null ? null : cause.toString()` ) (which typically contains the class and detail message of cause).
      Parameters:
        `cause` - the cause (which is saved for later retrieval by the `getCause()` method). (A `null` value is permitted, and indicates that the cause is nonexistent or unknown.)

    - #### CertPathValidatorException

          public CertPathValidatorException(String msg,
                                    Throwable cause)

      Creates a `CertPathValidatorException` with the specified detail message and cause.
      Parameters:
        `msg` - the detail message
        `cause` - the cause (which is saved for later retrieval by the `getCause()` method). (A `null` value is permitted, and indicates that the cause is nonexistent or unknown.)

    - #### CertPathValidatorException

          public CertPathValidatorException(String msg,
                                    Throwable cause,
                                    CertPath certPath,
                                    int index)

      Creates a `CertPathValidatorException` with the specified detail message, cause, certification path, and index.
      Parameters:
        `msg` - the detail message (or `null` if none)
        `cause` - the cause (or `null` if none)
        `certPath` - the certification path that was in the process of being validated when the error was encountered
        `index` - the index of the certificate in the certification path that caused the error (or -1 if not applicable). Note that the list of certificates in a `CertPath` is zero based.
      Throws:
        `IndexOutOfBoundsException` - if the index is out of range `(index < -1 || (certPath != null && index >= certPath.getCertificates().size())`
        `IllegalArgumentException` - if `certPath` is `null` and `index` is not -1

    - #### CertPathValidatorException

          public CertPathValidatorException(String msg,
                                    Throwable cause,
                                    CertPath certPath,
                                    int index,
                                    CertPathValidatorException.Reason reason)

      Creates a `CertPathValidatorException` with the specified detail message, cause, certification path, index, and reason.
      Parameters:
        `msg` - the detail message (or `null` if none)
        `cause` - the cause (or `null` if none)
        `certPath` - the certification path that was in the process of being validated when the error was encountered
        `index` - the index of the certificate in the certification path that caused the error (or -1 if not applicable). Note that the list of certificates in a `CertPath` is zero based.
        `reason` - the reason the validation failed
      Throws:
        `IndexOutOfBoundsException` - if the index is out of range `(index < -1 || (certPath != null && index >= certPath.getCertificates().size())`
        `IllegalArgumentException` - if `certPath` is `null` and `index` is not -1
        `NullPointerException` - if `reason` is `null`

  - ### Method Detail

    - #### getCertPath

          public CertPath getCertPath()

      Returns the certification path that was being validated when the exception was thrown.
      Returns:
        the `CertPath` that was being validated when the exception was thrown (or `null` if not specified)

    - #### getIndex

          public int getIndex()

      Returns the index of the certificate in the certification path that caused the exception to be thrown. Note that the list of certificates in a `CertPath` is zero based. If no index has been set, -1 is returned.
      Returns:
        the index that has been set, or -1 if none has been set

    - #### getReason

          public CertPathValidatorException.Reason getReason()

      Returns the reason that the validation failed. The reason is associated with the index of the certificate returned by `getIndex()`.
      Returns:
        the reason that the validation failed, or `BasicReason.UNSPECIFIED` if a reason has not been specified
