Hi Damyan,
I can still reproduce the problem. I can repeat nearly every attempt now and
can catch it on the debugger as below;
Daemon Thread [Thread-26] (Suspended (exception NullPointerException))
c.do(int...) line: not available
Repository.putStatement(int, int, int, int) line: not available
HashInferencer_2_593114.addStatement(int, int, int, int) line: 93
SailConnectionImpl$LocalThreadPool$LocalWorkerThread.doJob() line: 69
SailConnectionImpl$LocalThreadPool$LocalWorkerThread(ThreadPool$WorkerThread).run()
line: 40
this c (id=1187)
a null
b true
byte 101741
c int[2] (id=1234)
case 10000
char int[3][] (id=1205)
do 10000
else boolean[3][] (id=1235)
for EntityPool (id=1208)
goto 0
h int[3][] (id=1238)
i 3
if null
int 10000
j int[3][][] (id=1239)
k int[3] (id=1241)
long 0
new "/tmp/ontology/owlim.kb.281890959/xxx.pie/owlim-storage/" (id=1225)
try int[2][][] (id=1242)
arg0 int[2] (id=1202)
[0] 1074017706
[1] 1073915824
I can only assume that the difference between the native store and memory
store, is different transaction profile, which would point to a race somewhere.
Let me know if you need more info.
Thanks,
Carl

Subject: Re: [OWLIM-discussion] RuntimeException: error
Hi Carl,
just updated the distribution on
http://www.ontotext.com/owlim/swiftowlim-3.0.beta7-sesame-2.0.zip
the only difference is in the trree-3.0.beta7.jar - added few more sanity
checks and also guarded another relevant method with a synchronized section
it is very difficult to locate the problematic piece of code without a
reproducible scenario, sorry for the inconvenience.
about your observations for getting the 'error' exception more often with
org.openrdf.sail.nativerdf.NativeStore
I really do not get what could be the relation between sesame's own sail
implementations and ours - we do not interfere with these in any way... it
looks very strange indeed.
regards,
Damyan
