[jira] [Commented] (IGNITE-1011) GridDhtLockRequest marshals GridLeanMap with KeyCacheObjectImpl as a key

    [ https://issues.apache.org/jira/browse/IGNITE-1011?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14638216#comment-14638216 ] 

Denis Magda commented on IGNITE-1011:
-------------------------------------

Investigated and fixed.

Fix is the following. Instead of marshalling GridLeanMap now two separate arrays for keys and values are marshalled independently. This lets to avoid calling the hashCode().

Merged.

> This causes AssertionError during unmarshalling when KeyCacheObjectImpl is unmarshalled and hashCode() is called for it. HashCode fails because a wrapped value is used to determine the hash code but it's not unmrashalled.
> The issue exists for a long time and can reproduce when different conditions are met.
> In addition to GridDhtLockRequest other classes with the same issue must be found and fixed.
