My company's JSPs use a lot of comment blocks like this:

 <%----------------------------%>
 <%-- Blah blah blah         --%>
 <%----------------------------%>

Starting with Tomcat 7.0.32, this causes JasperExceptions:
org.apache.jasper.JasperException: Unterminated &lt;%-- tag

Up until 7.0.30, this worked fine. Perhaps this is introduced by bug 53713?

This is easy to reproduce. Create a jsp file with the following contents:
---
Start of page.
	<%----------------------------%>
	<%-- Blah blah blah         --%>
	<%----------------------------%>
End of page.
---
Visit this jsp page with 7.0.32 and 7.0.30 and see the difference.

I've been looking at the jsp specs to see if <%----------------------------%> might be invalid; perhaps a space is mandatory following the two dashes. But I didn't see that mentioned explicitly anywhere.
