collectd.java fails with default values

[wwentland]

Trying to use collectd.java on Debian results in the following error:

----------
          ID: /usr/lib/collectd/java.so
    Function: file.symlink
      Result: False
     Comment: File exists where the symlink /usr/lib/collectd/java.so should be

It would be muich appreciated if this insanity could be fixed in such a way that the formula works with the default settings.
