Description

I was working on some changes in Flink and on my workstation I have also JDK 14 installed.

When Flink is built using JDK > 8 and then run using JDK 8 the problem surfaces that the code crashes with the exception like this:

java.lang.NoSuchMethodError: java.nio.ByteBuffer.position(I)Ljava/nio/ByteBuffer;
	at org.apache.flink.core.memory.DataOutputSerializer.wrapAsByteBuffer(DataOutputSerializer.java:65) ~[classes/:?]
	at org.apache.flink.runtime.io.network.api.serialization.SpanningRecordSerializer.<init>(SpanningRecordSerializer.java:50) ~[classes/:?]
	at org.apache.flink.runtime.io.network.api.writer.RecordWriter.<init>(RecordWriter.java:98) ~[classes/:?]
	at org.apache.flink.runtime.io.network.api.writer.ChannelSelectorRecordWriter.<init>(ChannelSelectorRecordWriter.java:50) ~[classes/:?]
	at org.apache.flink.runtime.io.network.api.writer.RecordWriterBuilder.build(RecordWriterBuilder.java:53) ~[classes/:?]

This is a problem in the way JDK 9+ generates the code that is incompatible with using the JDK 8 runtime, even if during the build it was indicated that JRE 8 would be the target.

I have found several projects have ran into the exact same problem:

~~As indicated in the mentioned Jetty ticket the solution is quite simple:~~

~~The solution is to cast the ByteBuffer to Buffer when calling those methods:~~
((Buffer)byteBuffer).position(0);
