Hi Christine,
Thanks for the reply.
I had identified the same issue. So, applied the below fix in the custom
jar.
this.max = Float.parseFloat(max.replace("\"", ""));
this.min = Float.parseFloat(min.replace("\"", ""));
And, it worked. Thanks for confirming that this is an issue in solr 6.6.2
Regards
Kamal Kishore.
