BTW, is it possible to change this behavior from the command line or I have to recompile the VM?
Yep, it's possible to set the execution mode from the command line with the '-Xem' switch.
in any case, are there instructions on how to trigger different execution behavior on the VM some where in our docos/wikis?
There is some info here: http://wiki.apache.org/harmony/DrlvmCommandLineOptions And more information about configuring the Execution Manager (em) and pre-defined configurations: http://harmony.apache.org/subcomponents/drlvm/emguide.html Thanks, Pavel
