[jcifs] NullPointerException when trying to authenticate against domain name > 15 chars

[Michael B Allen]

This NPE is fixed in 1.2.18 to be released RSN.

java.lang.NullPointerException
	at jcifs.smb.SmbSession.getChallengeForDomain(SmbSession.java:109)
	at jcifs.http.NtlmHttpFilter.negotiate(NtlmHttpFilter.java:150)
	at jcifs.http.NtlmHttpFilter.doFilter(NtlmHttpFilter.java:114)
	at com.zylin.payback.app.servlet.AuthFilter.doFilter(AuthFilter.java:49)
	at org.apache.catalina.core.ApplicationFi

I changed the order of two lines in getChallengeForDomain that were createing a logical error when an UnknownHostException was thrown.
