Aiming for the JdkVersion class to support one generation ahead now, in order for the test suite to properly detect 1.7/1.8+ JVMs even when running against a JDK 1.9 preview at some point.
Allow WebSocketHandler methods to raise an exception.
By default we install ExceptionWebSocketHandlerDecorator, which logs
unhandled exceptions and closes the session. That decorator can be
extended or replaced.
Any exceptions that remain unhandled still (i.e. no exception handling
decorator), are caught in the lowest level before propagating to the
WebSocket engine or a SockJS transport handler and handled the same
way. That means default behavior is guaranteed but also fully
customizable.
This commit deletes the deprecated SimpleJdbcTestUtils class as well as
remaining usage of SimpleJdbcTemplate within the TestContext framework
and its test suite.

This commit deletes the deprecated @ExpectedException and
@NotTransactional annotations, supporting code, and related Javadoc and
reference documentation.

WebSocketHandler implementations:
- methods must deal with exceptions locally
- uncaught runtime exceptions are handled by ending the session
- transport errors (websocket engine) are passed into handleError
WebSocketSession methods may raise IOException
SockJS implementation of WebSocketHandler:
- delegate SockJS transport errors into handleError
- stop runtime exceptions from user WebSocketHandler and end session
SockJsServce and TransportHandlers:
- raise IOException or TransportErrorException
HandshakeHandler:
- raise IOException
HandlerProvider is now an interface that can be used to plug in
WebSocket handlers with per-connection scope semantics. There are two
implementations, of the interface, one simple and a second that creates
handler instances through AutowireCapableBeanFactory.
HandlerProvider also provides a destroy method that is used to
apply a destroy callback whenever a client connection closes.
ASM has been patched to accept 1.8 bytecode simply through removing an assertion. As a consequence, we have an embedded copy of the ASM sources now instead of jarjar'ing the original ASM jar. The sources originate from ASM 4.1; for CGLIB 3.0 compatibility, a further assertion has been removed.
