Eh eh APR on 5.5.14 on iSeries need I rebuild the APR/JNI part on 
iSeries and I didn't tried right now (as soon it will be ready, I'll

Right, but the idea (dream ?) is to be able to remove stuff not needed
for a very basic usage, TC 3.3.2 does that with modules/interceptors
files, TC 5.5.x allow some kind of configuration in its server.xml,
