             Summary: U.doInParallel may lead to deadlock
                 Key: IGNITE-10285
                 URL: https://issues.apache.org/jira/browse/IGNITE-10285
             Project: Ignite
          Issue Type: Bug
            Reporter: Dmitriy Govorukhin
         Attachments: dump.rtf

There are exist case when we can get a deadlock on the thread pool.
If we try doInParallel in the thread of sys-pool in the number of hreads==sys-pool.size we
lead to deadlock because threads in sys-pool will try doInParallel through the same sys-pool,
and they will wait on future infinitely because no one thread cannot complete operation doInParallel
which require threads from sys-pool.
