<p>It is highly recommended to use the latest NSS version when running PKCS11 tests. Improper NSS version may lead to unexpected failures which are hard to diagnose. For example, sun/security/pkcs11/Secmod/AddTrustedCert.java may fail on Ubuntu 18.04 with the default NSS version in the system. To run these tests correctly, the system property <code>test.nss.lib.paths</code> is required on Ubuntu 18.04 to specify the alternative NSS lib directories. For example:</p>

+# Depending on build platform, imported modules and optional parts of the build

+#
+# src/<module>/<share,platform>/classes/module-info.java.extra
+#
+# The contents of the .extra files are simply extra lines that could fit into

+/**
+ * Represents a stream of events.
+ * <p>
+ * A stream is a sequence of events and the way to interact with a stream is to
+ * register actions. The {@code EventStream} interface is not to be implemented
+ * and future versions of the JDK may prevent this completely.
+ * <p>
+ * To receive a notification when an event arrives, register an action using the
+ * {@link #onEvent(Consumer)} method. To filter the stream for an event with a
+ * specific name, use {@link #onEvent(String, Consumer)} method.
+ * <p>
+ * By default, the same {@code RecordedEvent} object can be used to
+ * represent two or more distinct events. That object can be delivered
+ * multiple times to the same action as well as to other actions. To use an
+ * event object after the action is completed, the
+ * {@link #setReuse(boolean)} method should be set to {@code false} so a
+ * new object is allocated for each event.
+ * <p>
+ * Events are delivered in batches. To receive a notification when a batch is
+ * complete, register an action using the {@link #onFlush(Runnable)} method.
+ * This is an opportunity to aggregate or push data to external systems while
+ * the Java Virtual Machine (JVM) is preparing the next batch.
+ * <p>
+ * Events within a batch are sorted chronologically by their end time.
+ * Well-ordering of events is only maintained for events available to the JVM at
+ * the point of flush, i.e. for the set of events delivered as a unit in a
+ * single batch. Events delivered in a batch could therefore be out-of-order
+ * compared to events delivered in a previous batch, but never out-of-order with
+ * events within the same batch. If ordering is not a concern, sorting can be
+ * disabled using the {@link #setOrdered(boolean)} method.
+ * <p>
+ * To dispatch events to registered actions, the stream must be started. To
+ * start processing in the current thread, invoke the {@link #start()} method.
+ * To process actions asynchronously in a separate thread, invoke the
+ * {@link #startAsync()} method. To await completion of the stream, use the
+ * awaitTermination {@link #awaitTermination()} or the
+ * {@link #awaitTermination(Duration)} method.
+ * <p>
+ * When a stream ends it is automatically closed. To manually stop processing of
+ * events, close the stream by invoking the {@link #close()} method. A stream
+ * can also be automatically closed in exceptional circumstances, for example if
+ * the JVM that is being monitored exits. To receive a notification in any of
+ * these occasions, use the {@link #onClose(Runnable)} method to register an
+ * action.
+ * <p>
+ * If an unexpected exception occurs in an action, it is possible to catch the
+ * exception in an error handler. An error handler can be registered using the
+ * {@link #onError(Runnable)} method. If no error handler is registered, the
+ * default behavior is to print the exception and its backtrace to the standard
+ * error stream.
+ * <p>
+ * The following example shows how an {@code EventStream} can be used to listen
+ * to events on a JVM running Flight Recorder
+ *
+ * <pre>
+ * <code>
+ * try (var es = EventStream.openRepository()) {
+ * es.onEvent("jdk.CPULoad", event -> {
+ * System.out.println("CPU Load " + event.getEndTime());
+ * System.out.println(" Machine total: " + 100 * event.getFloat("machineTotal") + "%");
+ * System.out.println(" JVM User: " + 100 * event.getFloat("jvmUser") + "%");
+ * System.out.println(" JVM System: " + 100 * event.getFloat("jvmSystem") + "%");
+ * System.out.println();
+ * });
+ * es.onEvent("jdk.GarbageCollection", event -> {
+ * System.out.println("Garbage collection: " + event.getLong("gcId"));
+ * System.out.println(" Cause: " + event.getString("cause"));
+ * System.out.println(" Total pause: " + event.getDuration("sumOfPauses"));
+ * System.out.println(" Longest pause: " + event.getDuration("longestPause"));
+ * System.out.println();
+ * });
+ * es.start();
+ * }
+ * </code>
