I have been playing a little bit around with jasper2 as released with tc 4.1.6 and I 
am haveing problems. 

I am using the OSCache taglibrary, and for some reason this does not work as it 
should. I cannot technically describe the problem, as I have not dug into it, but the 
tags are returning wrong values from cache. I think this has something to do with the 
tagpooling feature as this was not a problem in tc.4.1.3 version of jasper 2.

just wanted to bounce that of to somewhere. hopefully someone will pick this up, and 
check what's going wrong.
