Edit email template

[aas]

Hi. I try to change system email template issuereopened.vm which located in WEB-INF/classes/templates/email/html 

When I add #parse("templates/email/html/includes/fields/securitylevel.vm") nothing happens. There are no new string appear in mail. 

I tried to restart jira and also I changed 

velocity.properties:

1. Change class.resource.loader.cache from true to false
2. Uncomment (remove the # sign from) #velocimacro.library.autoreload=true

But no changes. May be I change wrong template?
