[jcifs] java.io.IOException: Failed to establish session

[Michael B Allen]

Hi Adam,

That is indeed a mistake. The code should read:

243                         if (log.level >= 2)
244                             ex0.printStackTrace(log);

I have adjusted this in my local copy and it will be included in the
next release.

Thanks for the feedback.

Mike
