Yes, this is currently expected behavior; the import mechanisms of XQuery and Java modules differ in various aspects. The customary way to proceed is to organize the Java calls in a single XQuery module. Both the Java class and the XQuery module can then optionally be bundled as JAR file (see [1]). Hope this helps, Christian [1] http://docs.basex.org/wiki/Repository#Combined Or should there only ever be a single such instance, regardless of how many times the module is imported? > > o Note: The functions used to initialize M1 are non-deterministic and > declared as such.
