-----------------------------------

             Summary: [IPC][Java] JDK 8 incompatibility with ByteBuffer.clear()
                 Key: ARROW-15913
                 URL: https://issues.apache.org/jira/browse/ARROW-15913
             Project: Apache Arrow
          Issue Type: Bug
          Components: Java
            Reporter: James Duong


There is an incompatibility with JDK 8 when Arrow is compiled with JDK 9 or higher as described here:

[https://jira.mongodb.org/browse/JAVA-2559]

 

"Java 9 introduces overridden methods with covariant return types for the following methods in java.nio.ByteBuffer that are used by the driver:
 * position
 * limit
 * flip
 * clear

In Java 9 they all now return ByteBuffer, whereas the methods they override return Buffer,
resulting in exceptions like this when executing on Java 8 and lower:

java.lang.NoSuchMethodError: java.nio.ByteBuffer.limit(I)Ljava/nio/ByteBuffer

This is because the generated byte code includes the static return type of the method, which is not found on Java 8 and lower because the overloaded methods with covariant return types don't exist.

The solution is to cast ByteBuffer instances to Buffer before calling the method."
