ClassCastException: com.codahale.metrics.Timer cannot be cast to com.codahale.metrics.Meter

Hi,

Thanks a lot for the detailed report.

The root cause of the exception that you're facing originates from the improper handling of multiple Metrics annotations for a single method.

I implemented that proper support for multiple Metrics annotation per method in commit 507235c and released version 1.0.0-rc.4 on Maven Central so that you can test the fix.

Let me know if that addresses your error case and if you need further assistance.

Hmmm. I upgraded to RC4 but now I can't even get the application to start because I get this error:

Same configuration and code samples as before. 😦

My mistake :-( I added the evaluation of the Metrics registry EL expression at class level though that leads to throwing that error when the class is having both non-static and static methods.

I've just reverted back to the previous behavior in commit a65d064 and added unit tests for that use case.

Would you mind testing your error case based on the head revision of the master branch before I release a newer version this time? ;-) Let me know otherwise I'll trigger a new release.
