Could we apply this in the 3.2.x dev streamm too?

> Currently null and empty string are treated differently in PropertiesHelper.  This makes it difficult to override values or provide templates for interpolation.  For example, in the mavenized testsuite I have the following entry in hibernate.properties:
> hibernate.connection.isolation ${jdbc.isolation}
> Attempts to set this to nothing do not work, because they become an empty string, which PropertiesHelper then tries to parse as an Integer.
