At hibernate search JMS cluster setup.

Anyone have an idea what is causing FSSlaveDirectoryProvider to fail with AccessDeniedException?
How to track this down?

File copy works a couple of times, in response to a master index update, then suddenly fails and keep on failing on the slaves.
It seems like hibernate is already locking the file when trying to do file copy.

Setup is;
Spring 4.3.4 on wildfly 8.
hibernate search 5.5.5
hibernate-core 5.1.1
Java 1.8
Windows 7

Configuration like JMS setup in https://docs.jboss.org/hibernate/search ... ms-backend
Ejb MDB at master node. Spring entityManagerFactory configures hibernate search.
3 nodes, refresh 2 min.

Problem was solved by changing default reader strategy from 'shared' to 'not-shared'

Thanks for reporting that: looking at the code I see it's not handling the Windows-style locking (we test mostly on other systems).

I've opened https://hibernate.atlassian.net/browse/HSEARCH-2690 and will fix it soon.
