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>, Int=
eger>>() {
                ....
}) ....

It works fine with Java 8, but using Java 11 I get this error stacktrace:

tor.visitNestHostExperimental(ClassVisitor.java:158)

67)
                at de.idsem.xploit.ief.control.FlinkETLOutputPipeline.execu=
te(FlinkETLOutputPipeline.java:66)

Could you please help with this issue?

Many thanks in advance and best regards
Jochen
