This seems rather bad to me. They are. However, if you have classes in a shared classloader used by bot= h webapps, and such a class is coded badly, references can leak from one we= bapp to another. BTW, jcifs.http.NtlmHttpFilter hasn't been viable for some years (no possib= ility of supporting NTLMv2), so you might want to use something that actual= ly works, such as waffle or Jespa. - Chuck THIS COMMUNICATION MAY CONTAIN CONFIDENTIAL AND/OR OTHERWISE PROPRIETARY MA= TERIAL and is thus for use only by the intended recipient.
