[hibernate-issues] [Hibernate-JIRA] Reopened: (HHH-2761) Handle null and empty string consistently in PropertiesHelper

Handle null and empty string consistently in PropertiesHelper ------------------------------------------------------------- Key: HHH-2761 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-2761 Project: Hibernate3 Issue Type: Improvement Components: core Reporter: Steve Ebersole Assignee: Steve Ebersole Priority: Trivial Fix For: 3.3 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.
