             Summary: NPE in TcpCommunicationSpi
                 Key: IGNITE-11293
                 URL: https://issues.apache.org/jira/browse/IGNITE-11293
             Project: Ignite
          Issue Type: Bug
            Reporter: Ivan Bessonov
            Assignee: Ivan Bessonov


Sometimes this exception is happening in "stopAllGrids" method in tests:
{code:java}
java.lang.NullPointerException

{code}
Reason is interruption thrown from TcpCommunicationSpi#reserveClient, SPI is already in invalid state at this point so "log" and some other fields are nulls.
