/**
* An exception indicating one of a variety of problems encountered when
* validating a certification path. <br />
* <br />
* A <code>CertPathValidatorException</code> provides support for wrapping
* exceptions. The {@link #getCause getCause} method returns the throwable,
* if any, that caused this exception to be thrown. <br />
* <br />
* A <code>CertPathValidatorException</code> may also include the
* certification path that was being validated when the exception was thrown
* and the index of the certificate in the certification path that caused the
* exception to be thrown. Use the {@link #getCertPath getCertPath} and
* {@link #getIndex getIndex} methods to retrieve this information.<br />
* <br />
* <b>Concurrent Access</b><br />
* <br />
* 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.
