    <p>This is interesting. Yes, dlmopen seems to support loading "in a

      namespace" which might achieve what you need.</p>

    <p>If that's the case (I suggest perhaps you do some experiments

      with C first), then it should be doable for you to create your own

      SymbolLookup that is based on dlmopen (you can call dlmopen using

      a downcall method handle, and get the library handle that way,

      then pass the library handle to "dlsym" to do the lookup).</p>

    <p>You can find an implementation of a dlopen-based lookup done

      using jextract here:</p>

    <p>It should be relatively simple (I hope) to take that code and

      tweak it so that it works on dlmopen.</p>

Anyway it seems that Panama can not directly handle dlmopen so the idea 

is to relay to JNA to connect to dlmopen first and then use Panama for a

 better memory management and performance.

What do you think?</pre>
