[jboss-jira] [JBoss JIRA] (DROOLS-1082) Querying for objects before any have been inserted prevents Class Aware Object Store from working properly

Querying for objects before any have been inserted prevents Class Aware Object Store from working properly ---------------------------------------------------------------------------------------------------------- Key: DROOLS-1082 URL: https://issues.jboss.org/browse/DROOLS-1082 Project: Drools Issue Type: Bug Affects Versions: 6.3.0.Final Reporter: James Elford Assignee: Mark Proctor In the presence of a class heirarchy, the {{ClassAwareObjectStore}} doesn't properly manage the relationships between {{SingleClassStores}} - specifically, it can become permanently corrupt if the following order of events occurs: * Insert object of type {{BaseClass}} * Query for objects of type {{SubClass}} ** Note that it's important this query is fully evaluated (e.g. copy it into a list) * Insert object of type {{SubClass}} Subsequent queries for objects of type {{BaseClass}} will _not_ return objects of type {{SubClass}}. If the intervening query for {{SubClass}} is left out, they would. The problem's in {{ClassAwareObjectStore#getOrCreateConcreteClass}}, where it tries to concretize an existing (non-concrete) store. It should go through the same "linking" process that gets done in the {{existingStore == null}} case (and half of which is done already in {{#getOrCreateClassStore}}).
