My config is like below, but the minSpareThreads not work

<Connector port="8080" address="${jboss.bind.address}"   

         maxThreads="500" maxHttpHeaderSize="8192"

         minSpareThreads="200" emptySessionPath="true" protocol="HTTP/1.1"

         enableLookups="false" redirectPort="8443" acceptCount="100"

         connectionTimeout="20000" disableUploadTimeout="true" />

after jboss server started, there is a warning log:

14:45:18,470 WARN  [Connector] Property minSpareThreads not found on the protocol handler.
