Hi again,
thanks for the help.
I run on Ubuntu Lucid Lynx, and tried java -Xmx512m -jar
CayenneModeler.jar but with the same result. It just took a while longer
for the heap to fill up. The stacktrace also shows a different position.
Anyway, this happens when I add an additional relationship between two
entities in my datamodel and do synch. I have included the DomainMap.
When I load it into cayenne, select the PositionTemplateDBEntity (the
newly added relationship is the "fromHeat" relationship to
HeatTemplateDBEntity, the "toPositions" relationship in
HeatTemplateDBEntity is the reverse relationship). When I press "Synch",
the GUI becomes unresponsive and after a minute or so I get the out of
heap space exception. I thought that I might have cause some loop in the
model, but anyway to eludes me.

In a Windows assembly run from .exe, -Xmx is passed by the executable launcher, and the user doesn't have much control (except that he can of course run it from command line, like the example above). So these are some significant differences.
