我有这个代码与Flink 0.10 SNAPSHOT，我得到一个我不太了解的运行时错误。
以下是代码：
DataStream<Thing> kafkaThings = env.addSource(
new FlinkKafkaConsumer082<Thing>(
"thing_data", // Topic to read from
new ThingSchema(reader), // Deserializer (provided as util)
props)
);
kafkaThings
.flatMap(new ThingFlatMapper())
.addSink(new ThingSink());
这是flatMap()步骤的运行时错误（我认为......）：

我认为它存在，因为我在addSource和ThingFlatMapper.flatMap方法中都设置了断点。它到达第一个但不是第二个。
我认为这是一个简单的配置错误，但错误消息并不完全有用（至少对我而言）。
思想？
（作为事后的想法，将我的构建依赖关系列在此处可能是有意义的 - 这里是我build.gradle中与flink相关的行：
compile "org.apache.flink:flink-clients:${project['flink.version']}"
compile "org.apache.flink:flink-connector-kafka:${project['flink.version']}"
compile "org.apache.flink:flink-core:${project['flink.version']}"
compile "org.apache.flink:flink-java:${project['flink.version']}"
compile "org.apache.flink:flink-optimizer:${project['flink.version']}"
compile "org.apache.flink:flink-streaming-java:${project['flink.version']}"
compile "org.apache.flink:flink-runtime:${project['flink.version']}"
compile "org.apache.flink:flink-java8:${project['flink.version']}"
flink.version设置为1.0-SNAPSHOT，我在IDEA内部运行它。
