> ChecksumByteBufferImpl's static initializer fails with:
> {code}
> ava.lang.reflect.InaccessibleObjectException: Unable to make field boolean
> java.nio.ByteBuffer.isReadOnly accessible: module java.base does not "opens
> java.nio" to unnamed module @46d56d67
> at
> java.base/java.lang.reflect.AccessibleObject.checkCanSetAccessible(AccessibleObject.java:354)
> at
> java.base/java.lang.reflect.AccessibleObject.checkCanSetAccessible(AccessibleObject.java:297)

> java.base/java.lang.reflect.Field.checkCanSetAccessible(Field.java:178)

> at
> org.apache.hadoop.ozone.common.ChecksumByteBufferImpl.<clinit>(ChecksumByteBufferImpl.java:51)
> {code}
> This exception appears with Java 17 and above as I tested it, it works for
> Java 9 and 11, however there is a way (according to the comment in the
> initializer) in Java 9 which we can use and which is identical to what we are
> doing with setting the field in Java 8.
> So I propose to use that from Java 9, and do not try to set the isReadOnly
> field accessible after Java 8.
