Description

Using Cayenne 1.2.2, jdk5.

In the modeler under cache configuration the "use shared cache" is disabled. This value I want to override programatically for example:

boolean useSharedCache = true;
DataContext context = DataContext.createDataContext(useSharedCache);
DataObjectUtils.objectForPK(context, Employee.class, 200);

This throws a nullpointer. Stack trace below.

Is this valid use of the API?

If I enable the "use shared cache" in the modeler this works fine, so its not a big issue.

Stacktrace:

Exception in thread "main" java.lang.NullPointerException
