Problem

Email Notification when a user is mentioned can break when the page body contains some special characters

Steps to reproduce

Setup Confluence with SMTP Mail Server
Create a Page using the Storage Format below:
table storage format.txt
Mention a user in the Comments column

Expected Result

Email notification received by the mentioned user should include the page body content normally

Actual Result

Error message below is in the email notification

Error: [com.ctc.wstx.exc.WstxLazyException] Unexpected character '<' (code 60) excepted space, or '>' or "/>" at [row,col {unknown-source}]: [1,327]

Also, when the affected page is updated, there could be an entry in atlassian-confluence.log similar to the below excerpt:

Suggestion

The email notification should be able to handle this since the Storage Format can be inserted using the Source Editor without complaining of any missing tags.

Workaround

As mentioned by Katharina below, a workaround is to remove the styling parameter from the <tbody> using the Source Editor plugin.
