Under the conditions:
- Model A has a Date field
- Model B extends Model A
- All rules have "java" dialect
When you set a value to the Date field of Model B in a Test Scenario, the Test scenario fails to run and throws the Exception.

This is because org.drools.ide.common.server.testscenarios.populators.FieldPopulatorFactory.isDate() uses Class.getDeclaredMethods which doesn't return super class methods.
private boolean isDate(String fieldName) { for (Method method : factObject.getClass().getDeclaredMethods()) { if (hasMutator(fieldName, method)) { if (java.util.Date.class.isAssignableFrom(method.getParameterTypes()[0])) { return true; } } } return false; }
BTW, if your rules use "mvel" dialect, Guvnor will load org.drools.base.mvel.MVELCompilationUnit class and its static block registers for Date and Calendar org.mvel2.DataConversion. Hence this issue will not occur.
static { //for handling dates as string literals DataConversion.addConversionHandler( Date.class, new MVELDateCoercion() ); DataConversion.addConversionHandler( Calendar.class, new MVELCalendarCoercion() ); }
