Bump - Would like to use this with later versions of Java without having to build it myself.

@highsource any news on this? At the moment we can't use your library with current java versions unfortunatly :(.

Thanks @kreftl !

In addition to your changes, for OpenJDK 15 to work I needed to do the following changes as well:

In pom.xml:

                                        <configuration>
-                                               <source>1.6</source>
-                                               <target>1.6</target>
+                                               <source>1.7</source>
+                                               <target>1.7</target>
                                        </configuration>

In npm/pom.xml:

-                                               <phase>generate-sources</phase>
+                                               <phase>prepare-package</phase>
