Hi folks, not sure if anyone noticed, but ktfmt is...

# ktfmt

Hi folks, not sure if anyone noticed, but ktfmt is (indirectly?) using some deprecated Unsafe APIs that will be removed from the JDK https://github.com/facebook/ktfmt/issues/533

Oh ok. How are you running it?

I don't see direct references to those classes in the code

[seb]

so I think it may be somewhere in the parser where it delegates to IJ/Kotlin

[seb]

I was trying to check the ktfmt version but the -h doesn't print it

[seb]

It is the latest available on homebrew tho

[seb]

https://formulae.brew.sh/formula/ktfmt says 0.54

Hey! Joining this thread. Is there a way to pass --sun-misc-unsafe-memory-access=allow to the Ktfmt invoked via the gradle plugin? I tried to add that to my org.gradle.jvmargs but that makes no difference... 😕

[Didier Villevalois]

OK, answering my own question. It seems that just making the work actions run with classloader isolation fixes the problem for me.

ktfmt {
    useClassloaderIsolation = true
}

But then I get java.lang.OutOfMemoryError: Compressed class space errors... 😢
