Error previously found in net 3.11.0 persisting in 3.11.1

I had found issue in Commons Net 3.11.0, whereby an 'untagged IMAP' 
reply of sufficient length would cause a Pattern mismatch and the 
following stack trace:

org.apache.commons.net.MalformedServerReplyException: Received

unexpected IMAP protocol response from server: '* OK The Microsoft
Exchange IMAP4 service is ready. [xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx]'.
at
org.apache.commons.net.imap.IMAPReply.getReplyCode(IMAPReply.java:119)
at
org.apache.commons.net.imap.IMAPReply.getUntaggedReplyCode(IMAPReply.java:130)
at org.apache.commons.net.imap.IMAP.getReply(IMAP.java:288)
at org.apache.commons.net.imap.IMAP._connectAction_(IMAP.java:152)

This was apparently fixed in 3.11.1.

Browsing the latest source code, I see this regex

  private static final String UNTAGGED_RESPONSE = "^\\* 
(\\S{1,80}).{0,160}";

If I am correct, this can match against a string of max length 240 chars ??

I am still seeing the error, even in 3.11.1.  Here is a recent example:

org.apache.commons.net.MalformedServerReplyException: Received 
unexpected IMAP protocol response from server: '* OK The Microsoft 
Exchange IMAP4 service is ready. 
[TQBXADIAUABSADIAMQAwADEAQwBBADAAMAAzADYALgBuAGEAbQBwAHIAZAAyADEALgBwAHIAbwBkAC4AbwB1AHQAbABvAG8AawAuAGMAbwBtAA==]'.

     at 
org.apache.commons.net.imap.IMAPReply.getUntaggedReplyCode(IMAPReply.java:130)

The string between the single quotes, which I suspect is the 'untagged 
response', is 265 bytes in length, which is longer than the regex 
definition.
