Hello, one of our clients has upgraded his Ubuntu 14.04 system to 16.0.4. Part of this upgrade was the change from OpenJDK7 to OpenJDK8, which is according to the documentation, no supported. But although he installed OpenJDK afterwards, Ciphermail (3.1.1) does not start, and the login windows does not appear. Here are a couple of lines from the log files: james.wrapper.log: > **ยทยทยท** > > --------------------------- > --\> Wrapper Started as Console > Java Service Wrapper Community Edition 64-bit 3.5.28 >   Copyright (C) 1999-2016 Tanuki Software, Ltd.
