hi in addition to the proposal by jukka to setup benchmarks i would like to suggest to soon setup integration testing that also test jr3 against the TCK.
imo it's important that we identify implementation details that violate the JCR specification early in the process. this will not only allow us to take conscious decisions regarding compliance violations but will also be very important to spot possible issues that will arise with migration of JCR applications to jackrabbit3. (thinking of apps like sling or cq that relying on quite some jr2 implementation details that are also reflected in the TCK :-). what do you think? angela
