Java has had AOT compilers since 2000, although they were commercial only, and nowadays there are some free beer ones via GraalVM and OpenJ9.
C# has always supported AOT compilation via NGEN, with the caveat that it needs to be done on-device and only dynamic linking is supported.
Besides NGEN, in the 20 years of .NET history, we had CosmOS AOT compiler, Singularity (whose tech landed on Windows 8 MDIL), Midori (whose tech landed on UWP .NET Native), Mono AOT (still going at it), Unity's IL2CPP, and now Native AOT.
