Igor, thank you for explanation. Now it seems that when the one thread tries to invoke GridCacheMapEntry#touch, the another one makes GridCacheProcessor#stopCache. If I am wrong, please feel free to correct me.
But it still does not clear for me why this fail appears after commit <https://github.com/apache/ignite/commit/51a202a4c48220fa919f47147bd4889033cd35a8> which is about MVCC. Moreover, NPE appears only with BinaryObjectException, and when the test is green, I can not find NPE in the log. Now I tried to run test locally 1000 times on the version before MVCC and could not find error on this concretely case (but it exists the another one <https://github.com/apache/ignite/blob/master/modules/core/src/test/java/org/apache/ignite/internal/processors/cache/query/continuous/CacheContinuousQueryOrderingEventTest.java#L426> which is about assertion on received events). пт, 30 нояб. 2018 г. в 13:37, Roman Kondakov <kondako...@mail.ru.invalid>: > Nikolay, > > I couldn't quickly find the root cause of this problem because I'm not > an expert in the binary metadata flow.
