+/**
+ * The Service Provider Interface (SPI) for the CertPathBuilder
+ * class. All CertPathBuilder implementations must include a class
+ * (the SPI class) that extends this class (CertPathBuilderSpi) and
+ * implements all of its methods. In general, instances of this class
+ * should only be accessed through the CertPathBuilder class. For
+ * details, see the Java Cryptography Architecture.<br />
+ * <br />
+ * <b>Concurrent Access</b><br />
+ * <br />
+ * Instances of this class need not be protected against concurrent
+ * access from multiple threads. Threads that need to access a single
+ * CertPathBuilderSpi instance concurrently should synchronize amongst
+ * themselves and provide the necessary locking before calling the
+ * wrapping CertPathBuilder object.<br />
+ * <br />
+ * However, implementations of CertPathBuilderSpi may still encounter
+ * concurrency issues, since multiple threads each manipulating a
+ * different CertPathBuilderSpi instance need not synchronize.
