Use Maven's Java for executable

[magno32]

From #21, when running inside an IDE (IntelliJ in my case), the plugin ignores whatever JDK we have selected for the project.

This can be solved in the plugin configuration with:

<configuration>
   ...
    <executable>${java.home}/bin/java</executable>
   ...
</configuration>

This feels like it should be the default behavior.

I've just came across same problem. Had to use the workaround above to be able to run the executable. Else it was using different java version than the one set in $JAVA_HOME.
