Bundle com.sun.jna not active on RPI: is it normal ? #1557

Open lolodomo opened 1 year ago

lolodomo commented 1 year ago

After starting OH snapshot 3556, all bundles are active except one:

 40 x Starting x  80 x 5.12.1                 x com.sun.jna

Is there a problem somewhere ?

J-N-K commented 1 year ago

What does diag 40 say?

lolodomo commented 1 year ago

Nothing:

openhab> diag 40
openhab>
lolodomo commented 1 year ago

I probably did not check since a long time on my RPI but I have in mind that all the bundles were "Active" after a OH start.

lolodomo commented 1 year ago

I just tried to install the snapshot 3556 on my PC but with no config except the modules Basic UI and RRD4j and in that case, the bundle com.sun.jna is active. So maybe something specific to RPI or to my OH setup ?

lolodomo commented 1 year ago

@kaikreuzer : should we care of that or not for OH4 release ?

kaikreuzer commented 1 year ago

As we do not even know if there is a general problem and if so, how to fix it, I would clearly answer with "no".

Works fine on my Pi.

Do you know what bundles are using this bundle ? Maybe my server setup doesn't need it ?

 40 x Starting x  80 x 5.12.1                 x com.sun.jna
 41 x Active   x  80 x 5.12.1                 x com.sun.jna.platform

JNA is used for using native libraries which can improve performance. It could be there are no native libs for your architecture so it's not used.

See also: https://github.com/java-native-access/jna

I also have a Pi 3 with a 32-bit OS in storage which I can fire up to do some testing if I find some time.

org.jline

It's a Karaf dependency that deals with handling console input, see: https://github.com/jline/jline3

io.methvin.directory-watcher

This is used for the WatchService, see https://github.com/openhab/openhab-core/pull/3004.

Works fine on my old Pi too:
