WildFly exception when L2C enabled

Question

I got this exception in wildfly-8.2 domain mode:

Caused by: Unable to acquire lock after [15 seconds] on key [app.entity.UserData#17568183] for requestor [GlobalTransaction::2482:remote]! Lock held by [GlobalTransaction::2135:remote] at org.infinispan.util.concurrent.locks.LockManagerImpl (line 198)

Here is the settings:

                </replicated-cache>
            </cache-container>
        </subsystem>

I am using XA-DataSource. What change is required to fix this issue?

I also get this exception with Wildfly 10.1 in domain mode and the same config.

If I disable the Cache for a specific entity there is no such exception.

The error occurs if in a first attempt to store the entity the transaction is rolled back due to some exception after the entity was flushed to the entity manager / database. And then in a second attempt (without exception after the flush) I run into this lock exception. So I think it might be related to some transaction stuff. A transaction that is not rolled back (correctly)!?

If the second attempt is started after about 2 minutes after the first attempt with the exception/rollback it works. This is probably because of the expiration timeout of 100.000 ms = 1min 40sec.

This post looks at first a lot like a "me too!", but there is an actual answer buried in there. You could probably reorganise it so that the answer is more obvious. Since you had the same problem, I expect others will too, and a few edits will make this answer easier to find and easier to use — Peter Hall, Jun 10 '17 at 22:11
