java.util.Map.get(string) returns null value if there is no value for the key searched. --------------------------------------------------------------------------------------- Key: HHH-5748 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-5748 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: ManagedSessionContext.java Method: existingSession, Line 124 Missing null check for "sessionMap.get( factory )", since java.util.Map.get(string) returns null value if there is no value for the key searched in the Map Class: NamedParameterSpecification.java Method: bind, Line 66 Missing null check for qp.getNamedParameters().get( name ), since get() method returns null value if there is no value for the key searched in the map. class: PersistentIdentifierBag.java Method: equalsSnapshot, Line 231 Missing null check on "old" in the statement "Object old = snap.get(id);", since get() method returns null value if there is no value for the key searched in the map.
