Openfire java.lang.IllegalArgumentException: Illegal JID: 异常解决
我在使用openfire集成现在系统的用户后，进入openfire的后台管理页面，选择Users/Groups（显示用户和组信息）时，出现了如下异常：

从网上找了资料才知道，在openfire的信息（应该主要是从数据库里查询出来的信息）不能含有空格，而我在集成的那个系统里面的用户名有一个如"成龙"是写成"成 龙"，所以在选择Users/Groups时出现了如下异常，只要将空格去掉就可以了，但有时如果真要用空格时，怎么办？
答如下：
Hi,
you likely need to use "\20" instead of " " in the JID. As you can see the log you did post contains "Contains prohibited code points." Anyhow I wonder why Spark fails to escape " " properly. My Spark beta/trunk version does not have this problem.
http://xmpp.org/extensions/xep-0106.html describes the mapping of escape characters.
