I've been using JBPM together with jdk1.5 since JBPM 3.0.2 without hassles
OK thanks Johan,
I was mainly asking because we ran the examples using jdk 1.4 and it was throwing runtime exceptions. With jdk 1.5 it was not, so we thought that there is a number of changes that affects jbpm.
Anyway, I guess the best way to test it is to create our own example project. Thanks again.
