Which two are advantages of using WLS JMS instead of using a third-party JMS Provider （Tibco， Sonic， etc.） ？ （）
A: JMS subsystem of WLS shares same JVM as core WLS application server， so application avoids the overhead of message serialization/de-serialization （necessary when using a 3rd party JMS provider with WLS）
B: WLS JMS ai always faster than 3rd party JMS providers
C: Unified operations and management tools across Application Server and JMS Provider will help with mangeability and diagnostics
D: WLS JMS more compliant with JMS spec than 3rd party vendors
