Description

We have a series of jobs that check forwards compatibility of our apps with the daily Beam SNAPSHOTs, and those jobs are failing since two days ago because a compatibility issue:

org.apache.beam.sdk.Pipeline$PipelineExecutionException: java.lang.NoSuchMethodError: java.nio.ByteBuffer.flip()Ljava/nio/ByteBuffer;
 at org.apache.beam.runners.direct.DirectRunner$DirectPipelineResult.waitUntilFinish (DirectRunner.java:368)
 at org.apache.beam.runners.direct.DirectRunner$DirectPipelineResult.waitUntilFinish (DirectRunner.java:336)
 at org.apache.beam.runners.direct.DirectRunner.run (DirectRunner.java:216)

This can be reproduced easily with a machine with only Java 8 and using Beam's archetype + SNAPSHOTs

mvn archetype:generate \
 -DarchetypeGroupId=org.apache.beam \
 -DarchetypeArtifactId=beam-sdks-java-maven-archetypes-examples \
 -DarchetypeVersion=2.26.0-SNAPSHOT \
 -DgroupId=org.example \
 -DartifactId=word-count-beam \
 -Dversion="0.1" \
 -Dpackage=org.apache.beam.examples \
 -DinteractiveMode=false

cd word-count-beam

mvn clean compile exec:java -Dexec.mainClass=org.apache.beam.examples.WordCount -Dexec.args="--inputFile=pom.xml --output=out"
