PyLucene : lucene.initVM() causes a segmentation fault on linux RHEL7

I installed PyLucene 4.10.1 (which I believe is the latest). However, when I call for initVM(), a SIGSEGV is raised and I have no idea what to do about it.

Here is the output :

[zzz@xxx gitCode]$ python
Python 2.7.5 (default, Oct 11 2015, 17:47:16) 
[GCC 4.8.3 20140911 (Red Hat 4.8.3-9)] on linux2


>>> import lucene
>>> lucene.initVM()

#
Aborted (core dumped)

The output of the core file is as follow :

Core was generated by `python'.
Program terminated with signal 6, Aborted.
#0  0x00007fc72e7ee5f7 in ?? ()

However, I noticed that Pylucene uses JRE 1.7 (from the above error message). When I run the following commands :

/usr/sbin/alternatives --config java
/usr/sbin/alternatives --config javac

it shows me that Java 1.8 is the default one. Could it be a compatibility problem ? If yes, how can I ensure stability with one version ?

I actually had two version of pylucene installed (4.9 and 4.10). Moreover, i compiled them with JDK 1.7 and was actually using 1.8 (even after switching to 1.7 it showed the SIGSEGV).

In the end, I just rm -rf both eggs (site/packages/lucene4.xxx.egg) and recompiled pylucene4.10 with JDK 1.8 and it worked.
