> OK - nearly there! Presumably because we're no longer hooked in to the container, OpenJPA was pumping out its log messages to system out. I set openjpa.Log to "commons" and, as desired, it now sends trace to java.util.logging. The only problem is that, when I set trace to "openjpa.*=all" I get a NullPointerException (that isn't there when trace is turned off):
