[jira] [Updated] (IGNITE-16057) Second read of array field from BinaryObject fail

["Nikolay Izhikov (Jira)" <ji...@apache.org>]

     [ https://issues.apache.org/jira/browse/IGNITE-16057?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Nikolay Izhikov updated IGNITE-16057:
-------------------------------------
    Description: 
Second read of array field fail and read some garbage.
This happen because when object read with handle stream position don't move to the end of already deserialized object.
So second array element is just random bytes from the middle of the stream.

        try (Ignite ignite = startGrid(1)) {

            BinaryObject arrObj = ignite.binary().toBinary(new TestClsWithArray(expArr));

            for (int i = 0; i < 10; i++)
