Return value check missing for ResultSet.next method
----------------------------------------------------

                 Key: HHH-5744
                 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-5744
             Project: Hibernate Core
          Issue Type: Bug
          Components: core
    Affects Versions: 3.6.0
            Reporter: Suresh Thummalapenta
            Priority: Minor



We developed a mining-based approach that recovers specifications for APIs of JavaSDK and uses those specifications to detect defects statically. In our study, we found that at various places, return checks are missing in the core component of Hibernate. It would be great if you could analyze and fix those issues.

Class: org.hibernate.id.GUIDGenerator.java
Method: generate, Line 67
Needs to check the return value of ResultSet.next() method, since it can return false if no rows exist and getString results in exception.
