> The ICU commit r612718 brings a regression in. In particular parallel using of static
method java.text.MessageFormat.format() leads to exception.
> Guess this is connected with non-synchronized usage of common code (static?).
> The failure is reproducible on multi-core system (8 cores, as well as 4 cores).
