java - Jersey 产生重复的日志消息

Question

有谁知道为什么 Jersey 会记录重复的消息？

重复的消息：

Apr 18, 2012 9:24:22 AM com.sun.jersey.api.core.PackagesResourceConfig init
INFO: Scanning for root resource and provider classes in the packages:

Apr 18, 2012 9:24:22 AM com.sun.jersey.api.core.ScanningResourceConfig logClasses
INFO: Root resource classes found:

Apr 18, 2012 9:24:22 AM com.sun.jersey.api.core.ScanningResourceConfig init
INFO: No provider classes found.

Apr 18, 2012 9:24:22 AM com.sun.jersey.server.impl.application.WebApplicationImpl _initiate
INFO: Initiating Jersey application, version 'Jersey: 1.9.1 09/14/2011 02:05 PM'

重复的日志消息是否表明我们的代码中有重复的内容？

谢谢
