Can you confirm that after you try to access the .jsp from the
browser, the timestamp on the .java file changes?
Are you deploying from a WAR file or exploded directory? Also, are any
of your JSPs in a .jar file (whether this is in a WAR file or not)?
There have been some recent reports of constant recompilation when
JSPs are in ZIP archives (and both .jar and .war are just .zip files
with certain expected entries within them).

Hmm, that looks like Tomcat is not generating good Java code. Would
you be able to post the entire .java file and the original .jsp? I
understand if that's not something you want to post publicly, so you
could email it directly to me if you feel better about that.
I read that you have performed a clean install of Tomcat, which is a
good step to take because this looks like a mismatched Jasper problem
or something.

This error happens when the original .class file can't be deleted
before re-naming an SMAP-loaded copy of the .class file. Can you
confirm that you have files called, for example,
userProfileBodyTile_jsp.java, userProfileBodyTile_jsp.class, and
userProfileBodyTile_jsp.javatmp ?
