solr_environment is not actually Optional

[Former user]

Leaving out solr_environment causes it to be undef, instead of an empty array.

solr.in.sh.epp then ends up calling size(undef) on line 174, which crashes.

A workaround is to set solr_environment => [].

Thank you. The value on the optional parameters needs to be set to undef in the epp. I will correct this today.
