It's not about "pick and choose" - we control the list that makes up a
stable release. 

I think we're looking at this problem from very different angles. 

I won't use xerces as an example ( it's a trap :-), but commons-logging
If some bugs are fixed (that affect tomcat) - we can recommend people to
update commons-logging to the specific version that we tested and includes
the fixes.

If we find a bug in jasper - we can test the fix against the "stable"
release and make a mini-release with only jasper. 

At any givent time, "Tomcat stable" will be the latest major release (
4.1.24 ) plus any additional patches that we test. All OS vendors have
"patches" that include updates to individual components ( well, Microsoft
has the huge service packs, but most other just update very specific
components ).  

Most of our components are relatively independent of each other and we 
have reasonably stable APIs, so "pick and choose on your own" could work,
but we can't support it.
