I've been working on migrating an application from Resin to
Tomcat-5.5.17 and have one particular JSP and bean that's got me stumped.
When using jsp:setProperty property="*", I get the following exception
and stack trace:

If I instead explicitly list each parameter, it works.
Suspecting a bean introspection issue, I wrote a little ditty that
checks the type of each bean property and the parameter type of its
setter method. All match. I also checked all request parameters
against matching property setters in bean and no mismatches.
What should I look for? I've reviewed
JspRuntimeLibrary.internalIntrospecthelper() and only candidates I see
are the method invocations.
Many thanks.
