IllegalArgumentException when performing rolling upgrades with transactional caches

Issue: JDG-4315

Description: It is not possible to perform a rolling upgrade with transactional caches. Upgrades fail and the following exception is written to logs: 

Caused by: java.lang.IllegalArgumentException: Cannot create a transactional context without a valid Transaction instance.
    at org.infinispan.context.impl.TransactionalInvocationContextFactory.createInvocationContext(TransactionalInvocationContextFactory.java:63)
[...]
    at org.infinispan.cache.impl.DecoratedCache.putIfAbsent(DecoratedCache.java:688)
    at org.infinispan.cache.impl.AbstractDelegatingAdvancedCache.putIfAbsent(AbstractDelegatingAdvancedCache.java:328)

Workaround: There is no workaround for this issue.

IOException occurs with Data Grid CLI on OpenShift

Issue: JDG-4292

Description: Running the Command Line Interface (CLI) from Data Grid pods running on OpenShift results in an java.io.IOException: Permission denied message.

For example, if you connect to the pod using oc rsh <pod-name> and then invoke the CLI from the /opt/infinispan/bin directory, when you quit the CLI the exception is thrown.

This exception is related to the Aesh component and can be safely ignored.

Workaround: Download Data Grid Server and use the CLI on your local host system. 

$ bin/cli.sh -c https://$SERVICE_HOSTNAME:11222/ --trustall

Data Grid on OpenShift continually restart after OOM exceptions

Issue: JDG-3991

Description: If out of memory exceptions cause Data Grid Server to terminate on OpenShift, the nodes cannot restart. The following exception is written to the pod log file: 

FATAL (main) [org.infinispan.SERVER] ISPN080028: Red Hat Data Grid Server failed to start java.util.concurrent.ExecutionException: org.infinispan.manager.EmbeddedCacheManagerStartupException: org.infinispan.commons.CacheException: Initial state transfer timed out for cache org.infinispan.LOCKS on <pod-name-id>
Copy to Clipboard Toggle word wrap

Workaround: There is no workaround for this issue.

Cannot authenticate with Data Grid Server from HotRod Store or NodeJS clients

Issue: JDG-3868

Description: If you use the HotRod store on Red Hat JBoss EAP to externalize session data to Data Grid, or if you use the Hot Rod NodeJS client, you cannot connect to Data Grid servers that require client authentication, which is the default configuration.

Workaround: Use the remote-store implementation with Red Hat JBoss EAP 7.3 in combination with server authentication. To use the HotRod store on Red Hat JBoss EAP, or to use Hot Rod NodeJS clients, you must disable Data Grid Server authentication.

Inconsistent query behavior when indexed caches contain non-indexed Protobuf entities

Issue: JDG-3972

Description: If a cache is indexed but contains a Protobuf entity that is not indexed, search operations on that cache return inconsistent results.

Workaround: There is no workaround for this issue.

Data Grid Conflict Resolution Performance

Issue: JDG-3636

Description: In some test cases, Data Grid partition handling functionality took longer than expected to perform conflict resolution.

Workaround: There is no workaround for this issue.

Data Grid Does Not Passivate JWS Sessions Correctly

Issue: JDG-2796

Description: When externalizing sessions from JBoss Web Server (JWS), sessions are not passivated correctly if using the FINE persistence strategy.

Workaround: There is no workaround for this issue.
