刚开始，启动bundle的时候出现错误，提示java.util.NoSuchElementException: Could not create a validated object, cause: org.apache.commons.net.ftp.FTPClient.setReaderThread。
在新版的commons-net2.2中，FTPClient没有继承TelnetClient，没有setReaderThread方法，所以出现如前文所示的错误信息。
使用两种方式解决：
1.把servicemix-ftp依赖的commons-net/commons-net/2.2改成org.apache.servicemix.bundles/org.apache.servicemix.bundles.commons-net/1.4.1_5。
2.安装org.apache.servicemix.bundles/org.apache.servicemix.bundles.commons-net/1.4.1_5，并在bundle中引入此版本的包。
通过上面两种方法的其中一种，bundle可以启动，一般情况下，文件也可以下载，但是会出现下面的异常。
EN:
At first, Occour exception on starting bundle，prompt"java.util.NoSuchElementException: Could not create a validated object, cause: org.apache.commons.net.ftp.FTPClient.setReaderThread".
Check new version "commons-net 2.2", the FTPClinet not extends from TelnetClient, it without "setReaderThread" Method, so happen this exception.
using to solutions to resolve this problem:
solution 1.Change "servicemix-ftp" feature's dependent "commons-net/commons-net/2.2" to "org.apache.servicemix.bundles/org.apache.servicemix.bundles.commons-net/1.4.1_5"(in file "${apache-servicemix-4.3.0}/system/org/apache/servicemix/apache-servicemix/4.3.0/apache-servicemix-4.3.0-features.xml" about "servicemix-ftp" section).
solution 2.install "org.apache.servicemix.bundles/org.apache.servicemix.bundles.commons-net/1.4.1_5", and import package for this version(Import-Package: org.apache.commons.net.ftp;version="[1.4,2)").
use any solution, the bundle can be started.currently the files will be downloaded. but sometimes will occour new exception(look stack),it may effect fild download.
