Luke 3.3.0 unable to open index from Solr 3.4.0 about luke HOT 8 CLOSED

same issue here... but getting "unknown format version -11"

Ditto. I'm using straight Lucene 3.4.0 (no Solr) and find Luke 3.3.0 unable to 
open Lucene 3.4.0 created indexes, with the 'unrecognized format - 3 in file 
"_d.fnm"' error. Worked fine until I updated from Lucene 3.3.0.

with java -jar ~/dev/utils/lukeall-1.0.1.jar I got "unknown format version -11"
with java -jar ~/dev/utils/lukeall-3.3.0.jar I got "unknown format version -3"

I'm having the same issue.  using Lucene 3.4 directly (no SOLR).
unrecognized format -3 in file "_51.fnm"

Having the same issue, using Solr 3.4

Here's a patch for the 3.3.0 branch.  You'll still need to update all the 
lucene 3.3.0 libraries to the ones from lucene 3.4.0.

Also attaching a lukeall.jar for those who don't feel like doing the work.

thank you for the patch.  it works :)

Thank you for the patch, I applied it with some additional changes in rev. 72. 
I'll put up the official release files shortly.
