Comment 2 Jaroslav Tulach 2013-07-23 10:29:45 UTC

Seems like a clash between
org.netbeans.modules.autosave.command.AutoSaveController(:123)
and regular save action:
org.openide.actions.SaveAction.performAction

Filesystem API properly throws an exception in case two threads try to obtain output stream for the same file object. From the point of view of filesystem API, this is not a bug - marking invalid.
