      Description

      It just isolate the Velocity macros but that's it. Any modification made to the context will end up in the next email.

      The most visible impact is when a lot of mails notification mails are generated in the same thread (for example when there is a lot of user like in myxwiki.org) you can end up with a VelocityContext instance reused for a huge number of script which is something that is not well supported: this issue was created after find a 650MB VelocityContext instance is a memory dump generated in myxwiki.org...

      The solution is generally to push/pop a cloned ExecutionContext.
