-------------------------------------
Summary: GridToStringBuilder#handleRecursion may cause NPE
Key: IGNITE-28747
URL: https://issues.apache.org/jira/browse/IGNITE-28747
Project: Ignite
Issue Type: Bug
Reporter: Egor Baranov
When recursion occurs on the end of string builder it may cause NPE.
Possible solution: override #i in class SBLimitedLength to execute the same
logic as in methods #a
Here is exception stack trace:
