I agree for short lived executions like tools etc.
That said value types are coming to Java as part of Project Vahalla (and tangentially related to Project Panama) and AoT will be shipping as part of OpenJDK proper which would likely allow Java to be suitable for some of those cases.
I would say Rust has a distinct advantage for language processing tasks however, not just because it's small runtime, compact memory layout etc but also because the existing body of work w.r.t language projects is very rich and well developed.
