This client is targeted at Java 6, and I'm afraid this bean was only added in Java 7. |

Indeed, that bean was introduced in Java7. |

@giannello could you use java reflection to access BufferPoolMXBean? If the class is not found (eg when you run with Java 6 Runtime), then return zeroes for the new metrics and if the class is found then use reflection to access the values. |
