Text output of release notes generates lots of extra whitespace when project has numerous unused issuetypes

Summary

In JIRA Software, when using the release note creation feature, you have two options HTML or text. When selecting the text option, the output can become full of lots of extra carriage returns and unneeded whitespaces

Environment

Only when selecting the text output, the HTML output does not appear to be effected

Steps to Reproduce

1. create a software project
2. make sure this project has at least 10 different issuetypes in it (the more issuetypes the project has, the easier it is to see this bug later)
3. Then make sure that all the issues in the release are of just a single issue type
4. create release notes

Expected Results

text output contains all the issues in the release with minimal extra whitespaces

Actual Results

It appears that the text output is creating a single carriage return for each issue type in the project, even if no issues of that type exist in the release.

Notes

This would be difficult to notice if you only had say 3-5 issuetypes in a project, but when you have 10-20 issuetypes in a project and the release only contains a single issue type, you can expect to see this specific problem.

Workaround

• This appears to be governed by the <jira-application-dir>/WEB-INF/classes/templates/jira/project/releasenotes/releasenotes-text.vm
• There looks to be an additional carriage return on line 40 of that template that is forcing this space in for each issuetype being looked for here.
