When this thing gets into productization it is better all around if we do use the same versions. While we can do some really cool things now through modules to have different versions of the same components floating around, I fear that we will get lazy, and before you know it we end up with dozens of versions of similar or the same components floating around, and that will become a support nightmare.<br><br>Andy<br><blockquote style="border-left: 2px solid rgb(16, 16, 255); margin-left: 5px; padding-left: 5px; color: rgb(0, 0, 0); font-weight: normal; font-style: normal; text-decoration: none; font-family: Helvetica,Arial,sans-serif; font-size: 12pt;"><br>Please consider I'm not familiar with the AS7 classloader isolation<br>details, but since we're not living under a stone our expectation was<br>that application code should be isolated from this; is this something<br>that should be enabled, or is Jackson "special" ?<br><br>Possibly the users reporting these issues are doing something wrong?
