As it turns out, while it doesn't break on JDK11, HBase UT fails due to this 
issue when running on JDK17.

What exact version of
1. JDK (Oracle or OpenJDK?)
2. Hadoop 
is used?

It looks like an intentional change in JDK 
https://bugs.openjdk.java.net/browse/JDK-8217225 since JDK12+12 not sure if 
it's backported to JDK11.
