<p>As I said, I believe this should be visible in JNI too
- but perhaps nobody would write code like this using
JNI. E.g. with JNI, since it's painful enough to write
one native method, developers tend to "lump" multiple
functionalities, e.g. error checking, in the same native
method implementation. Which, coincidentally, bypasses
some issues that might be visible when using debuggers
(so it is possible that this is a problem that debuggers
never had to worry too much about).</p>

<div>Something like this would happen in JNA and JNR based
code.</div>
<div>I am familiar with these; I'll port the original poster
program and push to Github.</div>

<p>Exactly - I believe something like that should probably be enough
to reproduce.</p>
<p>I've been trying to look at similar issues for JNA/JNR, but
couldn't find much - but again, this is a specific failure mode
(debug only) that occurs in a specific context (native interop).
So I'm not surprised if nobody stumbled into it (or maybe somebody
did, but did not report it).</p>
<p>As far as I can tell, jnr/ffi doesn't have any special handling
of LastError/errno.<br>
