[Linuxsampler-devel] JSampler java classes bugfixes?

[Andrew C <cou...@gm...>]

Hi all,

I'm running into some critical errors with openJDK/JRE versions 16/18 and
trying to run JSampler. It appears there are some older classes that are no
longer supported in these versions or perhaps need a bit more wriggling to
accommodate the JSampler code?

Exception in thread "AWT-EventQueue-0" java.lang.IllegalAccessError: class
org.jsampler.view.fantasia.basic.PixmapPane (in unnamed module @0x248d4f4a)
cannot access class sun.swing.plaf.synth.Paint9Painter (in module java.des
ktop) because module java.desktop does not export sun.swing.plaf.synth to u
nnamed module @0x248d4f4a

I know this is/was(?) Grishata's project and I lack the knowledge to even
begin trying to fix this up, but was wondering if anyone else has
encountered this and if there are workarounds for it?

The alternative, if I cannot get it working would have to be diving into
sending LSCP commands to Linuxsampler via Netcat. That should be fun! ;)

A question for Christian, but is it possible through LSCP to tell
Linuxsampler to open gigedit "Live" on an instrument, so as to edit in
real-time, or was that a special function of JSampler?

Cheers,

Andrew.

Yes, one of the following, but probably not an answer that you like:

- Use QSampler instead of JSampler.

or

- Use an older Java SDK.

or

- Try fixing the issue in JSampler's source code.

When you look at the Subversion repository [1] you will see that the last
change on JSampler was almost 10 years ago. It is almost a miracle that it
still worked for such a long time without any maintenance changes.

Or you just use QSampler, setup your session with mouse as usual, and if you
still want to use LSCP from the command line you can just save your session
with QSampler which saves it as LSCP file. So you would have an easy starting
point from there.

Sure! Both JSampler and QSampler control the sampler via LSCP. So everything
they do, you can do as well. In this case it is

My bad, I had forgotten about QSampler. I'll try that out instead and
perhaps hunt down an older Java SDK version if possible.

Cheers,
Andrew.

Maybe it is time to mark JSampler as orphaned (e.g. on the website) to make it 
more clear that nobody has been working on it for 10 years. If it no longer 
runs with a recent Java SDK version, then it is probably time to reflect the 
facts.

Hi Andrew,
You should be able to launch JSampler with latest JRE using the
following command:

java --add-exports java.desktop/sun.swing.plaf.synth=ALL-UNNAMED -jar
/path/to/Fantasia-0.9.jar

There might also be other module permission/access issues, which
should be easy to fix by using additional --add-exports and
--add-opens options, if needed.

Unfortunately, I don't have spare time for free projects anymore and I
don't think that I'll be able to find time to work on JSampler in near
future.

Regards,
Grigor.

Hi Grigor,

Thanks a bunch for that add-exports switch. JSampler is working fine now,
save for some creaky warning messages on JRE 18.

I migrated JSampler to github and added jigsaw support. Latest release
can be downloaded from here:

https://github.com/grigoriliev/jsampler-fantasia/releases

Note that you DON'T need to have Java installed to install Fantasia
using the provided installers, because Fantasia is packaged as a
self-contained Java application.

Good to know that this is working, thanks Grigor!

Any clue which JRE version starts to make this necessary?

I think it is Java 9 - when the module system was introduced (Jigsaw).
