| 31 | * An exception indicating one of a variety of problems encountered when |
| 32 | * validating a certification path. |
| 33 | * <p> |
| 34 | * A <code>CertPathValidatorException</code> provides support for wrapping |
| 35 | * exceptions. The {@link #getCause getCause} method returns the throwable, |
| 36 | * if any, that caused this exception to be thrown. |
| 37 | * <p> |
| 38 | * A <code>CertPathValidatorException</code> may also include the |
| 39 | * certification path that was being validated when the exception was thrown |
| 40 | * and the index of the certificate in the certification path that caused the |
| 41 | * exception to be thrown. Use the {@link #getCertPath getCertPath} and |
| 42 | * {@link #getIndex getIndex} methods to retrieve this information. |
| 43 | * |
| 44 | * <p> |
| 45 | * <b>Concurrent Access</b> |
| 46 | * <p> |
| 47 | * Unless otherwise specified, the methods defined in this class are not |
| 48 | * thread-safe. Multiple threads that need to access a single |
| 49 | * object concurrently should synchronize amongst themselves and |
| 50 | * provide the necessary locking. Multiple threads each manipulating |
| 51 | * separate objects need not synchronize. |
