Megan Knister created ARROW-12747:
-------------------------------------
Summary: Arrow's use of Netty library causes
UnsupportedOperationException with JDK16
Key: ARROW-12747
URL: https://issues.apache.org/jira/browse/ARROW-12747
Project: Apache Arrow
Issue Type: Bug
Components: Java
Affects Versions: 0.15.1
Reporter: Megan Knister
The Arrow vector library depends on netty, which throws the exception
*java.lang.UnsupportedOperationException: sun.misc.Unsafe or
java.nio.DirectByteBuffer.(long, int) not available.* In the documentation,
[it's stated that
s|https://github.com/apache/arrow/blob/master/java/README.md]etting
"-Dio.netty.tryReflectionSetAccessible=true" fixes the issue. This is true with
all java versions except with usage of the latest JDK16. The exception gets
thrown regardless of this system property setting when using JDK16.
Is there a fix for this?
Thanks!
