[~v.pyatkov] thanks, merged to master!
> Issue with P2P class loader
> ---------------------------
>
> Key: IGNITE-11698
> URL: https://issues.apache.org/jira/browse/IGNITE-11698
> Project: Ignite
> Issue Type: Bug
> Reporter: Vladislav Pyatkov
> Assignee: Vladislav Pyatkov
> Priority: Major
> Fix For: 2.8
>
> Time Spent: 40m
> Remaining Estimate: 0h

> Sometimes classes of remote query filter are incorrectly loaded.
> This happens because p2p context incorrectly matches
> {{CacheClassLoader#findClass}} with {{GridCacheDeploymentManager#p2pContext}}.
