James Duong updated ARROW-15913:
--------------------------------
Description:
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]
This pattern is used in at least MessageSerializer#readMessage(), but the
codebase needs to be examined anywhere ByteBuffer is being used.
"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."
