unable to update to jasperreports 4.7.0

I'm having an issue trying to upgrade from version 4.5.1 to 4.7.0: whenever I replace the old library with the new one, and I try to recompile our tomcat servlets which use the jasperreports functionality, I get an error saying that "class version is 50 but should be 49"

I'm compiling using JDK 5, is jasperreports 4.7.0 still compatible with that JDK? Or what could be the problem?

Restoring the old 4.5.1 version solves the problem, but I'd like to try to upgrade.
