You must be referring to the default compile-time length limitation of
"incremental" mode.  Please note that other cracking modes do not have
this limitation, and you're not supposed to be artificially limiting JtR
to using "incremental" mode only.

All of the existing builds of JtR with support for NT hashes patched
in should work for passwords longer than 8 characters - just not with
"incremental" mode indeed.

Please refer to these older postings for some relevant info:

BTW, you will likely get much better performance at NT hashes by
compiling JtR with a recent revision of the jumbo patch.
