Arjohn,
first of all, thanks so much for your work, we are really hoping to
release Piggy Bank 2.1.0 with the standard Sesame as we don't want to
ship our own patched version.
Unfortunately, "the wild" is telling you that Sesame reIndexing is, in
fact, far from being free of some serious bugs (or I'm not using it
correctly!)
So, here is what I did:
1) updated all the jars with the latest one shipped from sesame 1.2.2
(and removed the old ones, of course)
2) changed the way we initialize the SAIL to
static public LocalRepository createNativeRepository(
String id, File dir
)
throws ConfigurationException, IOException {
RepositoryConfig config = new RepositoryConfig(id);
SailConfig sail = new NativeRdfRepositoryConfig(dir.getCanonicalPath());
sail.setParameter("triple-indexes","spo, pos, osp");
config.addSail(sail);
config.setWorldReadable(true);
config.setWorldWriteable(true);
LocalService service = Sesame.getService();
return service.createRepository(config);
}
3) installed piggy bank 2.1.0 (which Sesame 1.2.2) on top of Piggy
Bank 2.0.4 (with Sesame 1.1.2)
4) and I get this exception when Sesame loads the SAIL:

Am I doing something wrong or is there something wrong in the
re-indexing code?
