Hi,

We have been using JServ 1.1b3 with our webmail (servlet, javamail 1.2,
JDNI/LDAP etc.) with Apache 1.3.9/mod_ssl/openSSL/GNUJSP1.0, RedHat Linux
6.0. Everything worked fine with both IBM JDK1.1.18 and JDK1.2 from Backdown
or Sun. We recently upgraded to JServ 1.1 final release and holly smokes
...:

1. With IBM JDK1.1.8, it just gave null result from making connection to
mail server
2. With JDK1.2RC3 from Blackdown (or RC1 from Sun), it gave CRASH DUMP:
