Doc Type: Bug Fix
Doc Text:
When the coordinator shuts down, it tries to install a new cache view that does not include itself. Because there are multiple nodes shutting down at the same time, two or more nodes can see themselves as the coordinator and will try to install conflicting views, failing and repeating the process for a very long time. This is now resolved by automatically rejecting outside cache views installation requests on the current JGroups coordinator. This way each one of the "coordinators" can shut down without interfering with the others.

I believe this was caused by ISPN-2186: when the coordinator shuts down, it tries to install a new cache view that doesn't include itself. Because there are multiple nodes shutting down at the same time, two or more nodes can see themselves as the coordinator and will try to install conflicting views, failing and repeating the process for a very long time.

The ISPN-2186 fix changes this by automatically rejecting outside cache views installation requests on the current JGroups coordinator. This way each one of the "coordinators" can shut down without interfering with the others.

Verified. I wasn't able to reproduce the bug with Infinispan that comes with JDG 6.0.1.CR1.
