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:
