0036842: jre8: js defaults containing Dates fail

DescriptionWhen there is a default JavaScript value evaluated in server and it use JavaScript Date objects it fails when running in Java 8.
Steps To Reproduce1. Open new Purchase Order Report
   -> ERROR:
      - Starting Date field is not defaulted (it should be default to today)
      - See openbravo.log:
ERROR org.openbravo.client.application.process.DefaultsProcessActionHandler - Error trying getting defaults and Filter Expressions for process: Cannot cast jdk.nashorn.internal.objects.NativeDate to java.util.Date

Proposed SolutionIn Java 8 JavaScript engine was changed from Rhino to Nashorn. JavaScript Dates evaluated in server, returned a java.util.Date in Rhino, but with Nashorn they are evaluated to jdk.nashorn.internal.objects.NativeDate. It will be necessary to implement proper casting (through reflection?) to support both Java 7 and 8.

fixes issue 36842: js defaults containing Dates fail in JRE8

  In Java 8 JavaScript engine was changed from Rhino to Nashorn. JavaScript Dates evaluated in server, returned a java.util.Date in Rhino, but with Nashorn they are evaluated to jdk.nashorn.internal.objects.NativeDate.

  This change caused a ClassCastException in JRE8 when invoking the methods of OBBindings which receive a java.util.Date as an argument. To fix the problem those methods have been overloaded by receiving an Object as argument. Therefore these methods will be invoked when working with JRE8, and we use reflection to retrieve the time information avoiding using classes which are not supported in JRE7.

tested with java 7 and 8 in both cases working correctly
