Andrey Mashenkov commented on IGNITE-12787:
-------------------------------------------
[~Pavlukhin],
There was a link to Oracle JDK ticket which looks outdated and broken.
Is there any proof that the fix is a part of all 1.8_x JDK versions?
I mean here not only OracleJDK, but OpenJDK and other vendors.
