Description

I'm parsing an arrow stream using the apache arrow java library 7.0.0 and I'm seeing this warning:

WARNING: An illegal reflective access operation has occurred
WARNING: Illegal reflective access by org.apache.arrow.memory.util.MemoryUtil (file:/home/ubuntu/.m2/repository/org/apache/arrow/arrow-memory-core/7.0.0/arrow-memory-core-7.0.0.jar) to field java.nio.Buffer.address
WARNING: Please consider reporting this to the maintainers of org.apache.arrow.memory.util.MemoryUtil
WARNING: Use --illegal-access=warn to enable warnings of further illegal reflective access operations
WARNING: All illegal access operations will be denied in a future release
 

I'm running java from openjdk 11 

java --version
openjdk 11.0.12 2021-07-20
OpenJDK Runtime Environment (build 11.0.12+0-adhoc..source)
OpenJDK 64-Bit Server VM (build 11.0.12+0-adhoc..source, mixed mode)
 

When moving to openjdk 17 I'm no longer able to run my code and I'm seeing this error 

Caused by: java.lang.reflect.InaccessibleObjectException: Unable to make field long java.nio.Buffer.address accessible: module java.base does not "opens java.nio" to unnamed module @315ea6a7
