Hey guys,

I was wondering if someone already tried to compile java programs natively.

There's the JLang project which compiles Java source code to LLVM-IR which then can be compiled natively. But JLang looks quite dead.

And there's GraalVM which offers a way to create native images.

As Java programs tend to be very slow on startup and generally pretty memory hungry I thought it might be interesting to have a look at this. :)

Hi @RubenKelevra,

while I would like speeding up java applications somewhat, the projects you suggested seem to me like a lot of PKGBUILD editing is needed (to an extent that you can call it a completely different package, IMHO).
I do not see this happening, since this would take up a considerable chuck of time, which I currently do not have (and probably never will). If we ever find something that can speed up java programs, without requiring massive manual efforts, I'm all ears.

@anonfunc I found one package already using this on the AUR. Looks like setting one enviromental variable is enough (in this case):

So it's more a make file replacement than a PKGBUILD patch... yeah but I see your point. :)

Please reopen this if there is anything we can do with flags or the shim (if that is a thing sometimes in the future).

For the time, this is not feasible.
