I can confirm that I see the same error message in the messages.log
file. When I change the following line in my patch from:

System.setProperty( "jna.boot.library.name", "jnidispatch" );

to

System.setProperty( "jna.boot.library.name", "jnidispatch.system" );

the INFO warning in the log file is gone.

I'm quite sure that we don't use an embedded jar of JNA somewhere in
Netbeans. I removed everything when I repacked the tarball. I also had
to make sure to patch libs.jna/nbproject/project.properties, so that the
build system doesn't try to install those external non-existent JNA
jars, otherwise the build would have failed.

I suspect that Netbeans' System.setProperty does something differently
and not what we expect or the patch for libjna-jni was incomplete.
