[jira] [Created] (IGNITE-12610) Disable H2 object cache reliably

Ivan Pavlukhin created IGNITE-12610:
---------------------------------------

             Summary: Disable H2 object cache reliably
                 Key: IGNITE-12610
                 URL: https://issues.apache.org/jira/browse/IGNITE-12610
             Project: Ignite
          Issue Type: Bug
          Components: sql
    Affects Versions: 2.8
            Reporter: Ivan Pavlukhin
             Fix For: 2.9


Internally H2 maintains a cache of {{org.h2.value.Value}} objects. It can be disabled by using "h2.objectCache" system property. There is a clear intent to disable this cache because the system property is set to "false" in {{org.apache.ignite.internal.processors.query.h2.ConnectionManager}}. But apparently it is too late, because the property is read by H2 internals before it. Consequently the object cache is enabled by default.

We need to set this property earlier.
