Tsz-wo Sze updated HADOOP-19334:
--------------------------------
Description:
According to [JEP 471|https://openjdk.org/jeps/471], sun.misc.Unsafe becomes
deprecated for removal in Java 23. So, the JDK versions before 23 should be
able to use it. The problem in the original description probably was due to the
Java 9 module problem (need the new --add-exports / --add-opens command line
options).
It is good to remove the use of

h3. Original description
when we build hadoop in JDK11 runtime based on
[HADOOP-19298|https://github.com/apache/hadoop/pull/7085] , JDK11 build is
failing as flowing due to: {{package sun.misc does not exist}} in.
This is because that package sun.misc is not supported after jdk11.
The purpose of this JIRA is to replace the .misc.Unsafe.
