Subject Re: RepositoryImpl closing sessions twice on shutdown
Date Thu, 01 Mar 2012 14:26:26 GMT
Seems like there is no wisdom or other interest in this issue, so I've logged it as https://issues.apache.org/jira/browse/JCR-3246
since I failed to find a solution for the problem apart from changing JR code.

Would be nice if this can be fixed in 1.4.1

Thanks,
Jan

> On shutdown sessions are being closed twice which lead to the exception being logged
as shown below. As far as I can tell RepositoryImpl has system sessions in the list of active
sessions which is why it tries to close them twice - first time when closing all active sessions
(RepositoryImpl.java:1078) and second time when disposing workspace (RepositoryImpl.java:1090).
