Hi all, I have implemented following code snippet with Apache Flink 1.8: flinkConfiguration.getEnvironment().readTextFile(outputFile.getAbsolutePath(), "ISO-8859-1") .flatMap(new FlatMapFunction<String, Tuple2<Map<ParameterBean, Object>, Integer>>() { .... }) ....
It works fine with Java 8, but using Java 11 I get this error stacktrace: at org.apache.flink.shaded.asm6.org.objectweb.asm.ClassVisitor.visitNestHostExperimental(ClassVisitor.java:158) at org.apache.flink.shaded.asm6.org.objectweb.asm.ClassReader.accept(ClassReader.java:541) at org.apache.flink.shaded.asm6.org.objectweb.asm.ClassReader.accept(ClassReader.java:391) at org.apache.flink.api.java.ClosureCleaner.cleanThis0(ClosureCleaner.java:115) at org.apache.flink.api.java.ClosureCleaner.clean(ClosureCleaner.java:75) at org.apache.flink.api.java.DataSet.clean(DataSet.java:186) at org.apache.flink.api.java.DataSet.flatMap(DataSet.java:267) at de.idsem.xploit.ief.control.FlinkETLOutputPipeline.execute(FlinkETLOutputPipeline.java:66) Could you please help with this issue?
