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:
Attempts to set this to nothing do not work, because they become an empty string, which PropertiesHelper then tries to parse as an Integer.
Could we apply this in the 3.2.x dev streamm too?
apply to 3.2 branch as well
