DragonFlyBSD platform support was added in java-native-access#1593 but the NativeLibrary fallback paths for versioned .so resolution, libc special-case loading, and 64-bit library search paths were not updated to include it. This causes NoClassDefFoundError when loading libc on DragonFlyBSD because the matchLibrary() fallback and the mapSharedLibraryName() handling only trigger for Linux and FreeBSD.

Summary
DragonFlyBSD platform support was added in #1593 but
NativeLibrarywas not updated to include DragonFlyBSD in the fallback paths that FreeBSD already uses.Problem
When loading
libc(or any library by short name) on DragonFlyBSD, the following fails withUnsatisfiedLinkError/NoClassDefFoundError:.sofallback (matchLibrary()) only triggers for Linux and FreeBSDmapSharedLibraryName()handling for.sofiles only covers Linux and FreeBSDFix
Add
Platform.isDragonFlyBSD()to all four locations inNativeLibrary.javawherePlatform.isFreeBSD()is checked. DragonFlyBSD is a FreeBSD derivative and uses the same library naming conventions.Testing
Discovered while porting OSHI to DragonFlyBSD. Verified that the workaround (using
"c"instead of"libc") resolves the loading issue, confirming the root cause is in these fallback paths.
