-/**
- * This example demonstrates the use of Ignite In-Memory Data Ignite cluster as a Hibernate
- * Second-Level cache provider.
- * <p>
- * The Hibernate Second-Level cache (or "L2 cache" shortly) lets you significantly
- * reduce the number of requests to the underlying SQL database. Because database
- * access is known to be an expansive operation, using L2 cache may improve
- * performance dramatically.
- * <p>
- * This example defines 2 entity classes: {@link User} and {@link Post}, with
- * 1 <-> N relation, and marks them with appropriate annotations for Hibernate
- * object-relational mapping to SQL tables of an underlying H2 in-memory database.
- * The example launches node in the same JVM and registers it in
- * Hibernate configuration as an L2 cache implementation. It then stores and
- * queries instances of the entity classes to and from the database, having
- * Hibernate SQL output, L2 cache statistics output, and Ignite cache metrics
- * output enabled.
- * <p>
- * When running example, it's easy to notice that when an object is first
- * put into a database, the L2 cache is not used and it's contents is empty.
- * However, when an object is first read from the database, it is immediately
- * stored in L2 cache (which is Ignite In-Memory Data Ignite cluster in fact), which can
- * be seen in stats output. Further requests of the same object only read the data
- * from L2 cache and do not hit the database.
- * <p>
- * In this example, the Hibernate query cache is also enabled. Query cache lets you
- * avoid hitting the database in case of repetitive queries with the same parameter
- * values. You may notice that when the example runs the same query repeatedly in
- * loop, only the first query hits the database and the successive requests take the
- * data from L2 cache.
- * <p>
- * Note: this example uses {@link AccessType#READ_ONLY} L2 cache access type, but you
- * can experiment with other access types by modifying the Hibernate configuration file
- * {@code IGNITE_HOME/examples/config/hibernate/example-hibernate-L2-cache.xml}, used by the example.
- * <p>
- * Remote nodes should always be started with special configuration file which
- * enables P2P class loading: {@code 'ignite.{sh|bat} examples/config/example-ignite.xml'}.
- * <p>
- * Alternatively you can run {@link ExampleNodeStartup} in another JVM which will
- * start node with {@code examples/config/example-ignite.xml} configuration.

+Apache Ignite LGPL Examples
+======================
+
+This folder contains code examples for various Apache Ignite functionality.
+
+Examples are shipped as a separate Maven project, so to start running you simply need
+to import provided `pom.xml` file into your favourite IDE.
+
+The examples folder contains he following subfolders:
+
+- `config` - contains Ignite configuration files needed for examples.
+- `src/main/java` - contains Java examples for different Ignite modules and features.
+- `src/main/java8` - contains additional set of Java examples utilizing Java 8 lambdas. These examples
+ are excluded by default, enable `java8-examples` Maven profile to include them (JDK8 is required).
+
+
+Starting Remote Nodes
+=====================
+
+Remote nodes for examples should always be started with special configuration file which enables P2P
+class loading: `examples/config/example-ignite.xml`. To run a remote node in IDE use `ExampleNodeStartup` class.
+
+
+Java7 vs Java8
+===============
+Some examples (not all) which can benefit from Java8 Lambda support were re-written with Java8 lambdas.
+For full set of examples, look at both Java7 and Java8 packages.

+/**
+ * This example demonstrates the use of Ignite In-Memory Data Ignite cluster as a Hibernate
+ * Second-Level cache provider.
+ * <p>
+ * The Hibernate Second-Level cache (or "L2 cache" shortly) lets you significantly
+ * reduce the number of requests to the underlying SQL database. Because database
+ * access is known to be an expansive operation, using L2 cache may improve
+ * performance dramatically.
+ * <p>
+ * This example defines 2 entity classes: {@link User} and {@link Post}, with
+ * 1 <-> N relation, and marks them with appropriate annotations for Hibernate
+ * object-relational mapping to SQL tables of an underlying H2 in-memory database.
+ * The example launches node in the same JVM and registers it in
+ * Hibernate configuration as an L2 cache implementation. It then stores and
+ * queries instances of the entity classes to and from the database, having
+ * Hibernate SQL output, L2 cache statistics output, and Ignite cache metrics
+ * output enabled.
+ * <p>
+ * When running example, it's easy to notice that when an object is first
+ * put into a database, the L2 cache is not used and it's contents is empty.
+ * However, when an object is first read from the database, it is immediately
+ * stored in L2 cache (which is Ignite In-Memory Data Ignite cluster in fact), which can
+ * be seen in stats output. Further requests of the same object only read the data
+ * from L2 cache and do not hit the database.
+ * <p>
+ * In this example, the Hibernate query cache is also enabled. Query cache lets you
+ * avoid hitting the database in case of repetitive queries with the same parameter
+ * values. You may notice that when the example runs the same query repeatedly in
+ * loop, only the first query hits the database and the successive requests take the
+ * data from L2 cache.
+ * <p>
+ * Note: this example uses {@link AccessType#READ_ONLY} L2 cache access type, but you
+ * can experiment with other access types by modifying the Hibernate configuration file
+ * {@code IGNITE_HOME/examples/config/hibernate/example-hibernate-L2-cache.xml}, used by the example.
+ * <p>
+ * Remote nodes should always be started with special configuration file which
+ * enables P2P class loading: {@code 'ignite.{sh|bat} examples/config/example-ignite.xml'}.
+ * <p>
+ * Alternatively you can run {@link ExampleNodeStartup} in another JVM which will
+ * start node with {@code examples/config/example-ignite.xml} configuration.
