-----------------------------------------

             Summary: Jdnc connection close exception left running threads
                 Key: IGNITE-23569
                 URL: https://issues.apache.org/jira/browse/IGNITE-23569
             Project: Ignite
          Issue Type: Improvement
          Components: jdbc
    Affects Versions: 3.0
            Reporter: Alexander Belyak
         Attachments: 24498.zip, bb.zip

In case of errors on Connection.close() method there is a running threads that prevents JVM from stopping:

 
{code:java}
"%172.24.1.210800%TcpClientChannel-timeout-worker" #43 prio=10 os_prio=0 cpu=427.72ms elapsed=4795.29s tid=0x00007f92240011e0 nid=0x6aa3 waiting on condition  [0x00007f92cc9f7000]
   java.lang.Thread.State: TIMED_WAITING (sleeping)
    at java.lang.Thread.sleep(java.base@17.0.12/Native Method)
    at org.apache.ignite.internal.future.timeout.TimeoutWorker.body(TimeoutWorker.java:106)
    at org.apache.ignite.internal.util.worker.IgniteWorker.run(IgniteWorker.java:108)
    at java.lang.Thread.run(java.base@17.0.12/Thread.java:840) {code}
 

Steps on how I get it:
 # Start single node cluster
 # Run TPC-H bench-base benchmark

Pls, find the stack trace of the benchbase client after getting the exception in 24498.jstack attachment.

It prevents utilities like benchmark or ETL script from stopping.
