It's used for indexing in joins. It looks like you are using the experimental multi-threading mode, I'd recommend you disable that, and try the latest 5.6.0.SNAPSHOT builds if you have problems.

We've been trying to schedule a release for some time now - but community releases are best effort, and a new bug that needs fixing keeps coming up. I'd say realistically I hope within next two weeks, but cannot guarantee that.

That warning is saying that for some reason drools isn't able to jit a constraint, i.e. to create a compiled constraint from an interpreted one. This is harmless in the sense that when this happens the compiled constraint gets automatically discarded and it continues being evaluated in interpreted mode. However interpreted constraints are slower than compiled ones, so it could be interesting to figure out why this is happening in your case. Do you have a test case that could allow me to reproduce this problem? Regards, Mario -- View this message in context: http://drools.46999.n3.nabble.com/rules-users-RightTupleIndexHashTable-tp...
