"String index out of range: -1" for hl.fl=* in Solr 1.4.1?

[Demian Katz]

I'm running into a strange problem with Solr 1.4.1 - this request:

http://localhost:8080/solr/website/select/?q=*%3A*&rows=20&start=0&indent=yes&fl=score&facet=true&facet.mincount=1&facet.limit=30&facet.field=category&facet.field=linktype&facet.field=subject&facet.prefix=&facet.sort=&fq=category%3A%22Exhibits%22&spellcheck=true&spellcheck.q=*%3A*&spellcheck.dictionary=default&hl=true&hl.fl=*&hl.simple.pre={{{{START_HILITE}}}}&hl.simple.post={{{{END_HILITE}}}}&wt=json&json.nl=arrarr<http://localhost:8080/solr/website/select/?q=*%3A*&rows=20&start=0&indent=yes&fl=score&facet=true&facet.mincount=1&facet.limit=30&facet.field=category&facet.field=linktype&facet.field=subject&facet.prefix=&facet.sort=&fq=category%3A%22Exhibits%22&spellcheck=true&spellcheck.q=*%3A*&spellcheck.dictionary=default&hl=true&hl.fl=*&hl.simple.pre=%7b%7b%7b%7bSTART_HILITE%7d%7d%7d%7d&hl.simple.post=%7b%7b%7b%7bEND_HILITE%7d%7d%7d%7d&wt=json&json.nl=arrarr>

leads to this error dump:

I've managed to work around the problem by replacing the hl.fl=* parameter with 
a comma-delimited list of the fields I actually need highlighted...  but I 
don't understand why I'm encountering this error, and for peace of mind I would 
like to understand the problem in case there's a deeper problem at work here.  
I'll be happy to share schema or other details if they would help narrow down a 
potential cause!

thanks,
Demian
