root cause
org.openrdf.repository.RepositoryLockedException: SAIL is already locked by: 15047@deepthought in /home/jeen/.aduna/openrdf-workbench/queries
org.openrdf.repository.sail.SailRepository.initializeInternal(SailRepository.java:103)
org.openrdf.repository.base.RepositoryBase.initialize(RepositoryBase.java:37)
org.openrdf.workbench.util.QueryStorage.<init>(QueryStorage.java:133)At first glance, it looks as if the workbench does not properly shut down the repository it uses for storing queries. Possible fix is a runtime shutdownhook, or switching to the new RepositoryProvider class (which takes care of shutting down cleanly for you).
