Dear Petrus,
the "patch" is available in this gist <>

It consists of 3 files:
 - one build script (
 - a patch file for jcc (pylucene_3_6-jcc-P3.patch)
 - a patch file for pylucene3.6 (pylucene_3_6-P3.patch)
in our environment the 3 files are located in 
and the output (i.e. patched Pylucene36) is created in
if you create this structure you may simply run
$ cd tools/build/pylucene
$ build

which will checkout Pylucene36 from SVN (in <root>/build), apply the patch files and
build JCC and PyLucene.
The Script is intended to run on Linux (or MacOS) - a diff binary and svn installation is

also easy_install(3) is needed to install the generated egg files -
besides the usual requirements for a PyLucene build (python3.4+, Java, gcc ...)

- the patch is "one way" i.e. the patched Pylucene36 won't work with Py27 anymore!
- the patch is for the old (and outdated) PyLucene36 version only - it has not yet been tested/ported
to newer versions of JCC/Pylucene
- the patched JCC has only been used/tested with PyLucene - not with any other Java library

A review of a core developer of JCC/Pylucene would also be good - I’ll ask Andi what he
thinks about this suggestion.

best regards,
