Hi Carsten,

Just a thought about something I've run into.  When a third party makes a
block or webapp that depends on the same lib but a different version, can
the jar indexing capability of jdk1.4 jar utility be employed to resolve the
issues?  It involves placing and maintaining a correct Class-Path: ... in
the jar's manifest and then running jar -i *.jar.

Also does anyone know if the indexing really does or would affect the speed
of bringing up a wepapp and say Tomcat?

I have no experience with this but have been interested in it. Would this necessarily introduce a dependency on 1.4? (in which case I doubt we'd decide to go that way?) Or would it only require jar-ing with 1.4
and writing backwards compatible classloaders which respect the indexing?
