hi, i have dkpro-statistics with version 2.0.1 in our pom file. when i import the library and use the related classes, i receive'the following error and couldn't find a work around: "Exception in thread "main" java.lang.UnsupportedClassVersionError: org/dkpro/statistics/agreement/distance/IDistanceFunction : Unsupported major.minor version 52.0" i use java1.7.

The latest version requires Java 8. Solutions:

update your JDK
checkout the trunk and downgrade the parent POM + replace Java-8-specific code snippets (shouldn't be many so far)
use an older release (not recommended)
