> Key: FLINK-12389
> URL: https://issues.apache.org/jira/browse/FLINK-12389
> Project: Flink
> Issue Type: Bug
> Components: Table SQL / Runtime
> Affects Versions: 1.8.0
> Reporter: Yu Yang
> Priority: Major
>
> We try to write a simple flink sql program using "select .. from " statement, and encounter a compile exception.
> *Caused by: org.codehaus.commons.compiler.CompileException: Line 110, Column 38: Cannot cast "java.nio.ByteBuffer" to "java.lang.String"*
> Further debugging shows that the following flink-generated code snippet caused problem:
> {code}
> final java.lang.reflect.Field field_com$pinterest$utzv2$thrift$RealtimeSpendValue_segmentIds =
> org.apache.flink.api.java.typeutils.TypeExtractor.getDeclaredField(
> com.pinterest.utzv2.thrift.RealtimeSpendValue.class, "segmentIds");
> ...
> boolean isNull$5 = (java.nio.ByteBuffer) field_com$pinterest$utzv2$thrift$RealtimeSpendValue_segmentIds.get(in1) == null;
> java.lang.String result$4;
> if (isNull$5) {
> result$4 = "";
> }
> else {
> result$4 = (java.lang.String) (java.nio.ByteBuffer) field_com$pinterest$utzv2$thrift$RealtimeSpendValue_segmentIds.get(in1);
> }
