PyLucene error with IceTea / JDK / JRE

I have followed the installation instructionrs http://bendemott.blogspot.de/2013/11/installing-pylucene-4-451.html for pylucene using the latest pylucene-4.9.0.0.

And when i tried to to lucene.initVM(), I get the following error:

alvas@ubi:~$ python

Type "help", "copyright", "credits" or "license" for more information.
>>> import lucene
>>> lucene.initVM()

And the file http://pastebin.com/6B8FyC4Z

Is there something wrong with my IceTea configuration? or my JDK? or JRE?

How should I resolve the problem?

So I took a look at your stack trace, and I don't think the issue was specifically pyLucene. In the stack trace, you see this error:

siginfo:si_signo=SIGSEGV: si_errno=0, si_code=1 (SEGV_MAPERR), si_addr=0x0000000000000000

If you look at the first part, SIGSEGV, that means you have a segmentation fault somewhere in your system. SEGV_MAPERR is the specific error, which means that OpenJDK was trying to map memory to an object and failed. This could've been caused by not enough memory, a bad pagefile/virtual memory, bad address space, or even a bad library. Why it worked on another machine could be anything. Core dumps are really useful, so if you can run

ulimit -c unlimited

that will help give you something to look at. Was this in a VM or on a physical machine? I've seen random sigsegv in my Ubuntu VMs if they don't have enough memory allocated for various Java tasks. I saw this on my ESXi hypervisors specifically, and I noticed it the most was when ESXi started to perform memory swapping. I was able to resolve this by increasing memory, rebooting the VM, and making sure my hypervisor wasn't swapping memory. Let me know if that helps. :)

Edit: I also noticed that if the underlying storage provider had poor performance, that would impact with swap data and I feel that was also am impact with sigsegv issues.
