 * An exception indicating one of a variety of problems encountered when

 * A {@code CertPathBuilderException} provides support for wrapping

 * exceptions. The {@link #getCause getCause} method returns the throwable,

 * if any, that caused this exception to be thrown.

 * <b>Concurrent Access</b>

 * 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.
