ParameterMessageInterpolator is the message interpolator to use when EL is not available/wanted. Various issues, including HV-1131, show that EL is not a hard requirement and that there are valid use cases of applications that don't have this dependency.
On the other hand, ParameterMessageInterpolator is logging at the WARN level:
Is there a way to disable that log statement? Right now it's part of the interpolator constructor and there's no way to get around that.
Maybe there's a way to make users aware of that fact (logs, failing hard?) when interpolating messages requiring an EL implementation?
