Was there ever a condition where the listeners wouldn't run?

Hi,
I tested JSF since some people said the listener wasn't being found
(the said listener is declared in a TLD which is in a JAR). I found it
worked very well, but the way it is handled is funny because of the
serialized cache:
- Catalina will cache but will not bother when adding/removing JARs
(for example, if you have the cardemo example, you realize the JSF
JARs are not there, and after the first falied run, you add the JARs
in /WEB-INF/lib or lib; it is not going to work unless tldCache.ser is
deleted from the work dir; there's a last modified check, but
obviously it cannot detect this sort of changes, which is going to be
the most frequent), and could easily give the impression TLDs are not
properly found and parsed (note: the bahavior is the same with 5.5)
- Jasper will reparse everything anyway, scanning all JARs in the
process ( :( )
Avoiding scanning and parsing TLDs is of course faster, but I would
like to removing caching in Catalina (with a flag to enable it
explicitly), and add a feature where Catalina will pass an ArrayList
of JARs containing TLDs to Jasper as an attribute like the annotation
processor (if the attribute is not there, Jasper will rescan
everything, so it should remain compatible). This should make up for
the slowdown to some extent. Unfortunately, I cannot find a cool trick
to allow caching, but if someone has an idea ...
