prims/jvm.cpp:

JVM_ENTRY_NO_ENV(void*, JVM_LoadLibrary(const char* name, jboolean throwException))
  //%note jvm_ct
  char ebuf[1024];
  void *load_result;
  {
    ThreadToNativeFromVM ttnfvm(thread); // <-- This construct has the thread enter _thread_in_native.
    load_result = os::dll_load(name, ebuf, sizeof ebuf);
  }

A thread running in state _thread_in_native cannot capture a stack trace, because tagging of artefacts (klasses, methods etc.) is a function of an epoch, which evolves during safepoints.

In addition, for virtual threads, this can lead to assertions in the Access API, such as the following:

# A fatal error has been detected by the Java Runtime Environment:
#
# Internal Error (/workspace/open/src/hotspot/share/oops/accessBackend.cpp:224), pid=77881, tid=86379
# assert(state == _thread_in_vm || state == _thread_in_Java || state == _thread_new) failed: Wrong thread state for accesses: 4
