> Affects Versions: 1.1.0
> Reporter: Nikolaas Steenbergen

> in the scala shell, local mode, version 1.0 this works:
> {code}
> Scala-Flink> var b = env.fromElements("a","b")
> Scala-Flink> b.print
> Scala-Flink> var c = env.fromElements("c","d")
> Scala-Flink> c.print
> {code}
> in the current master (after c.print) this leads to :
> {code}
> java.lang.NullPointerException
