To prevent the crash, I've modified javapre.i line 197:
iBase * ibase = (iBase *)$1.Ref;
void * ptr =
ibase->QueryInterface(iSCF::SCF->GetInterfaceID($1.Type), $1.Version);
by
iBase * ibase = dynamic_cast<iBase *>((iBase *)$1.Ref);
if (ibase != NULL) {
void * ptr =
ibase->QueryInterface(iSCF::SCF->GetInterfaceID($1.Type), $1.Version);
...
}
This way it doesn't crash anymore... but still the console object is null...
