But still the bytecode of 1.6 is not compatible with 1.5 (unless the 
compatibility flag is set - at least I hope that it is then).
Avoiding the new APIs and the different annotation rules alone is not enough. 
Or do I miss something here?

No I am not (have not checked that - lazy), but at least the version of the 
junit jar that comes along with my eclipse build on my suse linux did not 
work with JRE 5, even if its manifest claims to be built with 1.4.
