Subject [jira] [Commented] (MYFACES-4225) [perf] Cache whether a library exists in ExternalContextResourceLoader
Date Fri, 13 Apr 2018 17:47:00 GMT


Christian Beikov commented on MYFACES-4225:

Is there any reason for that?

I'd suggest when the project stage is PRODUCTION, this should be cached. Maybe this could
be done by installing an {{ExternalContextWrapper}} that caches all resource lookups? I just
see that parsing a XHTML causes many exceptions to be thrown internally which negatively affects
