Hi Matthias,
Getting back to this far too late... Sorry.

I installed the llvm package to get the /usr/bin/llvm-symbolizer

Brought back the visibility=hidden settings, seems they do no harm to
msan . However the removal of -Wl,--exclude-libs,ALL is needed.
I think there might be ways around that to tell the linker to actually
keep the symbols we need. If you want to pursue integrating msan into
the JDK build properly, we can explore that. If so, we should also check
for the presence of llvm-symbolizer in configure and warn if it is
missing (though I guess the real question is if it is present at
runtime...).
Seems msan is unhappy about the thread != nullptr in line 81 of
jfrThreadLocal.cpp
Thread* thread = Thread::current_or_null();
_parent_trace_id = thread != nullptr ? jvm_thread_id(thread) :
(traceid)0;
Not sure why this is reported as uninitialized ?
I have no idea.
Did you pursue this any further, or did you give up?
