Critical Description
Tapestry 4.1 seems to be compiled by java 5 and is no longer java 1.4 compatible. And I haven't seen a statement telling that it shouldn't be.
I have a simple test case build and run by maven to reproduce my assumption. I also have a .zip file containing the full example if needed:
