Some users report having problem parsing unicode-1-1-utf-7 (aka utf-7) emails. JIRA breaks with a stacktrace like:

The solution

Hopefully one day, Sun will include support for this encoding natively (see this Sun bug report, but in the meanwhile you can install a library to get this working. Installation is quite simple:

  1. Download the jutf7 jar from http://sourceforge.net/projects/jutf7
  2. Copy the jar to your $JAVA_HOME/jre/lib/ext directory. No other directory will do - it has to be in this (lowest)classloader to be picked up.
  3. Restart JIRA (or Confluence, or whatever is parsing the emails).
