Failed Jelly Run does not escape HTML from the Jelly INPUT

When there are HTML tags in the Jelly input, for example in an issue description, these tags will be interpreted in the errordump.

It can break the display and also prevent the developer from reading the error message.

Please convert special characters into html entities to avoid these problems.

Thanks

[EDIT] :
I triggered this bug a while ago, so I had troubles reproducing it.

This sample will raise it :

<JiraJelly xmlns:jira="jelly:com.atlassian.jira.jelly.JiraTagLib">
<jira:CreateIssue description="

<form method='post' action='&amp;'>

<input type='text' size='150'/>

</form>

" issueType="Bug" priority="Major" project-key="PYWP" summary="sum" />
</JiraJelly>

This one is tricky : If you remove & from the action, the code will get parsed correctly

I will provide other code examples, if you need so.
