[jira] [Created] (IGNITE-7978) Recovery from WAL may result in JVM crash

Denis Mekhanikov created IGNITE-7978:
----------------------------------------

             Summary: Recovery from WAL may result in JVM crash
                 Key: IGNITE-7978
                 URL: https://issues.apache.org/jira/browse/IGNITE-7978
             Project: Ignite
          Issue Type: Bug
            Reporter: Denis Mekhanikov


{{GridCacheDatabaseSharedManager}} checks page tags, when acquiring page write locks. If the actual tag doesn't match the expected value, then {{PageSupport#writeLock}} method returns 0 pointer, which results in JVM crash.

A proposed solution here is to make {{GridCacheDatabaseSharedManager}} ignore the page tag, i.e. use {{restore=true}} option in {{PageSupport#writeLock}} method.
