 * A <code>CertStoreException</code> provides support for wrapping
 * exceptions. The {@link #getCause getCause} method returns the throwable, 
 * if any, that caused this exception to be thrown.<br />

 * <b>Concurrent Access</b><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.
