> Query expression compilation heavily relies on {{contextClassLoader}} from
> thread this expression is compiled by. The problem is that
> {{java.lang.Thread#getContextClassLoader}} may return {{null}}. In this case
> query fails with following error:
> {code}
> Caused by: org.apache.ignite.internal.lang.IgniteInternalException:
