| * amongst themselves and provide the necessary locking before calling the |
| * wrapping {@code CertPathBuilder} object. |

| * However, implementations of {@code CertPathBuilderSpi} may still |
| * encounter concurrency issues, since multiple threads each |
| * manipulating a different {@code CertPathBuilderSpi} instance need not |
| * synchronize. |
