Issue about jna

[plusls]

I found that [email protected]+scala.2.13.6 in curseforge contains com.sun.jna, after I install fabric-language-scala, it will cause jna register fail, print

I read the source code in jna, and found that Native.getConversion return -1.

https://github.com/java-native-access/jna/blob/7ae36913c7094f14fc841555c8dd36ffdb67a3ee/src/com/sun/jna/Native.java#L1731

And I write the test code:

        ImBlocker.LOGGER.info("check WinNT.HANDLE {}", PointerType.class.isAssignableFrom(WinNT.HANDLE.class));
        ImBlocker.LOGGER.info("check WinDef.HWND {}", PointerType.class.isAssignableFrom(WinDef.HWND.class));
        ImBlocker.LOGGER.info("check WinDef.HWND {}", WinNT.HANDLE.class.isAssignableFrom(WinDef.HWND.class));

Before install fabric-language-scala:

[16:53:05] [Render thread/INFO]: check WinNT.HANDLE true
[16:53:05] [Render thread/INFO]: check WinDef.HWND true
[16:53:05] [Render thread/INFO]: check WinDef.HWND true

After install fabric-language-scala:

[16:54:31] [Render thread/INFO]: check WinNT.HANDLE false
[16:54:31] [Render thread/INFO]: check WinDef.HWND false
[16:54:31] [Render thread/INFO]: check WinDef.HWND true

This is a serious problem that affects mod that uses JNA. Could we get backports of the library to fix all latest major versions of Minecraft?

Honestly, just a copy/paste of the Kotlin project seems to be in order. That repo has received significantly more love than this one, and the improvements could be easily transferred.

[modmuss50]

Just to confirm this was caused by the latest update to scala? If so I can remove the broken build.

[modmuss50]

The kotlin project is also a right pain to maintain, if it ever requires more work than just changing version numbers I will most likely rewrite to use a groovy gradle buildscript.

This has been an issue for ~3 years (if my git blame is correct, it was introduced in 1751ea7). It was rare enough that we just shrugged it off until now, when some people bothered to get to the bottom of it.

[modmuss50]

Ok thanks for looking into it. I will take a look ASAP.

This makes me unable to use this mod on m1

[sleepy-evelyn]

This issue is still an absolute pain. Means if a single modpack has one mod that relies on Fabric Language Scala you can't play it
