Hi Tobi, > It turns out, that Jenkins has a problem with it
I see: I could not reproduce because the new "try/catch with resources" code was not yet on the master branch. I share your surprise that somehow overriding the scijava.jvm.version property is not enough. I have run into similar subtle issues with property overrides for dependency versions, but more recently was unable to reproduce them. It probably has something to do with how the POMs are resolved, and would be worth our time to understand better so that we avoid similar issues in the future.
