The free AOT compilers have atrocious compile times (far, far worse than even Rust or Scala) and don't support all of the features so library support is extremely fragile. A lot of extremely popular Java libraries make extensive use of runtime reflection and none of the AOT compilers handle it well without a lot of extremely error prone manual configuration.
I actually like Java and the JVM but if AOT compilation and efficient memory usage is what you want Java is definitely not the language to use.
