[SNMP4J] How to resolve this question

[胡清钟]

hello
         I download the version of snmp4j_tool-v1.6d ,and use this sentence:
	       "SNMP4J -a MD5 -A huqingzMd5 -u huqingz -x DES -X huqingzDes -p GETNEXT 12.1.3.5 1.3.6.1.2.1.2.2.1.2"
		but the response is "The -X options are non-standard and subject to change without notice" ,why ?

　　　　　　　　Thanks.
