I am also experiencing problems with resin 4.0.29 - when javamelody is enabled, 
some jsp requests just create a blank page (empty response).
Do you also get a blank page?

Can you submit an example of jsp to reproduce the problem?
And what is your exact version of resin?

For whatever reason unknown to me, Resin does not like to have a 
"META-INF/web-fragment.xml" file inside the javamelody jar file.

If this file is inside the jar file then Resin seems to think that the webapp 
is a servlet api v2.5 or v2.4 compatible webapp, and not a servlet api v3.0 
compatible webapp.
And then Resins does not compile the jsp correctly. It displays "${1+10}" for 
your index.jsp.

If you remove the "META-INF/web-fragment.xml" from the javamelody jar, using 
web.xml only, (and if you remove the WEB-INF/work directory of the webapp), 
then it works.
Resins compiles the jsp correctly. It displays "11" for your index.jsp.
And also the javamelody monitoring works.
For example, the attached webapp (test.war) has a javamelody jar file without 
META-INF/web-framgent.xml and it works correctly.

By the way, I think that you have found a Resin bug. There is certainly no 
reason why a META-INF/web-fragment.xml such as [1] would cause Resin to think 
of a v2.5 compatible webapp.
You could submit an issue in their issue tracker (http://bugs.caucho.com/) and 
attach the test.war and test-ko.war examples.
