Description Kevin Rose 2012-05-20 14:32:34 UTC

When using a ServletContainerInitializer with a HandlesTypes annotation if any of the classes specified in the HandlesTypes annotation are not available due to a missing jar file catalina will crash with a "java.lang.ArrayStoreException: sun.reflect.annotation.TypeNotPresentExceptionProxy".

Would you expect anything else to happen?

Comment 2 Kevin Rose 2012-05-22 03:09:36 UTC

I would like to see tomcat gracefully shutdown with an error message prudent to the reason instead of an ArrayStoreException.

As it is possible for any library to contain a ServlerContainerInitializer if for any reason a need dependency in any library is missing this is possible to occur.

Comment 3 Mark Thomas 2012-06-11 21:00:24 UTC

Note the spec requires that the web application is permitted to start in this case.

This has been fixed in trunk and 7.0.x and will be included in 7.0.28 onwards.
