--- Comment #1 from Mark Thomas <ma...@apache.org> --- In theory, you should be safe swapping API implementation classes but it is likely you will see different behaviour as different implmentations will have fixed different bugs. Personally, I wouldn't swap implementations. I'd rather stick with a known problem than risk an untested, unsupported combination. >From a Tomcat PoV we are normally only going to support folks that are using the Tomcat API implementations. In this case the reason you see better performance is that Glassfish hasn't added the required support for imports in the version you are using. Looking at the Glassfish source it appears that this is partially fixed (statics don't appear to be supported yet) in trunk which should be in the next release. In terms of solving the performance problem I think we need to cache "Not Found" results as well. I'll take a look. -- You are receiving this mail because: You are the assignee for the bug. --------------------------------------------------------------------- To unsubscribe, e-mail: dev-unsubscr...@tomcat.apache.org For additional commands, e-mail: dev-h...@tomcat.apache.org
