-----------------------------------------
Summary: MVCC: Concurrent cache stop can cause vacuum failure.
Key: IGNITE-10263
URL: https://issues.apache.org/jira/browse/IGNITE-10263
Project: Ignite
Issue Type: Bug
Components: cache, mvcc
Reporter: Andrew Mashenkov
The issue can be easily reproduced with IgniteCacheIncrementTxTest in Mvcc mode.
Vacuum.cleanup() fails on cctx.gate().enter() if cache is stopped concurrently.
ctx.gate().enter() method fails with IllegalStateException right after readLock
has been taken.
So, this lock will be never released and prevent writeLock being taken on node
stop.
Replacing enter() with enterIfNotStopped() resolve the issue, but most likely
we should release readLock on failure inside gateway.enter().
