TextEvaluator.java:[12,50] cannot access org.deeplearning4j.models.paragraphvectors.ParagraphVectorse[m  
[ERROR] e[1;31m bad class file: C:\Users\lenovo.m2\repository\org\deeplearning4j\deeplearning4j-nlp\1.0.0-M2.1\deeplearning4j-nlp-1.0.0-M2.1.jar(org/deeplearning4j/models/paragraphvectors/ParagraphVectors.class)e[m  
[ERROR] e[1;31m class file has wrong version 55.0, should be 52.0

I am using java 8 and 1.0.0-M2.1.jar. The pom section is listed below

```
    <dependency>

            <!-- properties section in pom.xml-->
            <dl4j-master.version>1.0.0-M2.1</dl4j-master.version>
	<nd4j.backend>nd4j-native</nd4j.backend>

```

Does 1.0.0-M2.1 supports Java 8 or higher version is required ? Changing it to 1.0.0-M2 doe not have the problem
