Resteasy Netty Buffer Leak

with netty resteasy deployment and durring run of micro-benchmark test,
getting following WARN

2014-05-14 16:32:19 ERROR ResourceLeakDetector:176 - LEAK: ByteBuf.release() was not called before it's garbage-collected. Enable advanced leak reporting to find out where the leak occurred. To enable advanced leak reporting, specify the JVM option '-Dio.netty.leakDetectionLevel=advanced' or call ResourceLeakDetector.setLevel()

Since by default, only one of 100 buffers under track for memory leak, that's why this issue not immediately visible
