Description

The org.openrdf.sail.helpers.SailBase, a common superclass of the memory, native and rdbms store, does not register its connections properly. Connection removal from the registration map is properly synchronized, but additions are not. In highly concurrent environments, this leads to warnings of the form: "tried to remove unknown connection object from store".
