Adrian Nistor commented on ISPN-2589:
-------------------------------------
On cache leave (shutdown) the node _sometimes_ receives the new CH in which all its data
segments are removed and it will (needlessly) attempt to discard that data (or move it to
L1 if enabled) but fails due to NPE because some cache components are already shut down
(DistributionManager). This affects both DIST and REPL caches because the state transfer
code is common but it was never expected that segments are ever removed in a REPL cache
(can happen only during shutdown). This last CH update is irrelevant and is not always
received, thus not always reproducible and failing to process it is just logged as a
warning. The best way to fix this is to ensure LocalTopologyManager does not deliver CH
updates after leave.
NPE in InvalidateL1Command
--------------------------
Key: ISPN-2589
URL: https://issues.jboss.org/browse/ISPN-2589
Project: Infinispan
Issue Type: Bug
Components: Core API, State transfer
Affects Versions: 5.2.0.Beta5
Reporter: Thomas Fromm
Assignee: Adrian Nistor
Fix For: 5.2.1, 5.3.0.Final
Attachments: standalone_node0001.xml
The used cache is an REPL_SYNC one w/o L1 and Optimistic TX.
Can't provide unit test, just saw it in my logs.
