Redisson throws NPE after upgrading to version 3.25.0 and higher

[Marley98]

Redisson throws NullPointerException after upgrading to version 3.25.0 or higher.

java.lang.NullPointerException: Cannot invoke "java.util.concurrent.CompletableFuture.join()" because "connectionFuture" is null at org.redisson.command.RedisExecutor.handleError(RedisExecutor.java:614) at org.redisson.command.RedisExecutor.execute(RedisExecutor.java:200) at org.redisson.command.CommandAsyncService.async(CommandAsyncService.java:605) at org.redisson.command.CommandAsyncService.readAsync(CommandAsyncService.java:357) at org.redisson.RedissonBucket.getAsync(RedissonBucket.java:141) at org.redisson.RedissonBucket.get(RedissonBucket.java:136)

The exception occurs relatively rare (< 0.1% error rate) so it becomes more visible with high load.
At peak, our application makes 28k req/min and has up to 300 active cache connections.

The latest working version is 3.24.3. The issue occurs on every newer version including the latest one (3.26.1)

Redis version
ElastiCache engine version 7.0.7

Redisson version
3.26.1
