The following warning appears when completing a user task:

17:45:47,670 WARN [org.hibernate.hql.internal.ast.HqlSqlWalker] (http-localhost/127.0.0.1:8080-1) [DEPRECATION] Encountered positional parameter near line 1, column 85. Positional parameter are considered deprecated; use named parameters or JPA-style positional parameters instead.

I have seen this issue already before, so it's not limited to just this task operation. So if possible this should be fixed on multiple places.

I am aware of the fact that this bug is not a serious one, but we should tend to have BPMS server logs free of unnecessary warnings.

My env:
jBPM 6 CR1
EAP 6.1
H2
