Only the Eclipse JDT compiler preserves the generic type information necessary to use the entire Lambda Expressions feature type-safely. -Other compilers such as the OpenJDK's and Oracle JDK's `javac` throw away all generic parameters related to Lambda Expressions. This means that types such as `Tuple2<String,Integer` or `Collector<String>` declared as a Lambda function input or output parameter will be pruned to `Tuple2` or `Collector` in the compiled `.class` files, which is too little information for the Flink Compiler. +Other compilers such as the OpenJDK's and Oracle JDK's `javac` throw away all generic parameters related to Lambda Expressions.

How to compile a Flink job that contains Lambda Expressions with the JDT compiler will be covered in the next section.
