[opencms-dev] Error on CmsHtmlMail

[Francis]

After migration from 7.05 to 7.5.2, I receive this error when I try to 
send a mail whith CmsHtmlMail.

javax.servlet.ServletException: org.opencms.mail.CmsHtmlMail.send()V

In opencms.log we can find :

java.lang.NoSuchMethodError: org.opencms.mail.CmsHtmlMail.send()V

Have you heard of problems like this?

Thank you
