The libraries are no longer present on the filesystem.   `NativeLibraries::loadLibrary` checks for the file existence before calling `JVM_LoadLibrary`.   Such check no longer applies on Big Sur.   This proposes that on macOS >= 11, it will skip the file existence check and attempt to load a library for each path from java.library.path and system library path.

I’m curious about this issue.

I never load system libraries directly. I load my own libraries (that support JNI entry points) and the system loader loads the necessary system frameworks that they were linked against.

What’s different in this case that motivates loading system libraries directly from Java?
