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.
