Yakov Zhdanov commented on IGNITE-1111:
---------------------------------------
Sergey,
I looked at the code here -
https://www.codatlas.com/github.com/lambdalab-mirror/jdk7u-jdk/HEAD/src/windows/classes/java/net/DualStackPlainSocketImpl.java?line=250
It seems to be an issue somewhere in JDK code. We get NPE because of some
private member in package local class is null. Very weird.
Can you quickly search in JDK bug database and post the stack trace there if
same bug missing?
