Hello Krzysztof,
It is not at all clear how this one slipped through, but I can confirm
that it is a bug when using the MINUS operator (in conjunction with a
certain kind of optimisation).
We have made an emergency patch, which I will send to you in a
separate email.
Sorry for the inconvenience,
barry

Hello,
We tried to use Owlim SE 5.2 but StackOverflowError is now thrown for
some SPARQL queries (it was OK for Owlim SE 5.1). Below is the
simplified version of query that causes this problem (it seems to be
independent of repository content):
select * where {
{
?uri <uri:notExistingPredicate> ?object.
} UNION {
?uri <uri:notExistingPredicate1> ?object2.
MINUS { ?object2 a <uri:someType> } .
}
}
Stacktrace:
java.lang.StackOverflowError
