GraalVM can generate native images BUT
not yet cross platform
Source: https://github.com/oracle/graal/issues/407
36. ✴ Analyze statically all code
✴ Compile reachable code
✴ Generates native code
✴ Package it with SubstrateVM

37. ✴ Framework subset of JVM
✴ No JIT
✴ No optimization
✴ No Graal neither any related with bytecode
✴ Just runtime: GC, threads, I/O, ...

54. ✴ Evaluate static code at compile time
✴ No dynamic code
✴ Some strange exceptions appears
✴ Take long time to generate executable
✴ Only for Mac/Linux/Win 64 bits

✴ Almost all features work
✴ Some bugs / features to work, like:
✴ Does not support compilation of non-
reducible loops
58. ✴ Sometimes requires lot of changes / rewrite
✴ No metaprogramming
✴ Closures requires manual config
✴ Grape doesn't work on standalone native
images
