Tamás Bunth commented on NIFI-7296:
-----------------------------------
I could reproduce the bug using CentOS 7.8.2003,
java-11-openjdk-11.0.7.10-4.el7_8.x86_64.
The problem is related to an openJDK bug[1], which is already fixed, and
backported to OpenJDK 11.0.8.
The problem lies on having a new entry in CLDR which is "America/Nuuk". Nuuk is
renamed from Godthab, but this change has to be addressed in OpenJDK as well
(apparently, they link the existing data to this new entry).
Since it's not "our" bug, and the affected java versions are narrow, I would
close this issue.
