pocking into the code i think the FileDictionary class is the culprit:
It takes an InputStream as a ctor argument but never releases the
stream. what puzzles me is that the class seems to allow a one-time
iteration and then the stream is useless, unless i'm missing smth. here.
is there a good reason for this or rather a bug?
should i move the topic to the dev list?

hi,
i'm using the suggester with a file like so:
<searchComponent class="solr.SpellCheckComponent" name="suggest">
<lst name="spellchecker">

when trying to replicate i get the following error message on the
slave side:

so i dug around it and found out that the solr's java process holds a
lock on the autocomplete.dictionary file. any reason why this is so?
thx,
running:
solr 3.5
win7
