[Building Sakai] DynaBeanAdapter can't be cast to FieldAdapter

[D. Stuart Freeman]

Here's all the places that I have reflectutils:

./components/turningtool-pack/WEB-INF/lib/reflectutils-0.9.10.jar

./webapps/providers/WEB-INF/lib/reflectutils-0.9.14.jar
./webapps/polls-tool/WEB-INF/lib/reflectutils-0.9.14.jar

I only see blogwow in there once, and no shared. The mix of 0.9.10 and
0.9.14 wouldn't cause it, right since they're in separate classloaders?
