Hello, Sergey and other. I followed the instruction in issue description and I didn't get AssertionError, but got exception looks like in issue in "Caused by" part. I attached exception part of my logs in JIRA like file "Ubuntu_OpenJDK_1.8.111.txt" (name is my configuration). <https://issues.apache.org/jira/secure/attachment/12849099/Ubuntu_OpenJDK_1.8.111.txt> https://issues.apache.org/jira/browse/IGNITE-4364
So if this behavior is fine I think issue can be closed. Otherwise Could you, Sergey, to lend me a hand and tell me does time out is invalid behavior or some thing else?
