> URL: https://issues.apache.org/jira/browse/IGNITE-2009
> Project: Ignite
> Issue Type: Task
> Components: cache, interop
> Affects Versions: ignite-1.4

> Problem: when query is executed, it is cache in thread-local in
> parsed/prepared form. It has reacheable reference to IgniteKernal. As a
> result IgniteKernal cannot be collected until the thread dies. If this thread
> is from a pool, it could be a real leak.
> Can we employ WeakReferences here?
