Subject UnsupportedOperationException from org.apache.flink.shaded.asm6.org.objectweb.asm.ClassVisitor.visitNestHostExperimental using Java 11
Date Thu, 04 Jul 2019 13:34:03 GMT
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 de.idsem.xploit.ief.control.FlinkETLOutputPipeline.execute(FlinkETLOutputPipeline.java:66)

Could you please help with this issue?

Many thanks in advance and best regards
Jochen
