RM quit working again

Sometime in the last month or so RM quit working. Was running 2.06 build 6 iirc on xubuntu 18.04lts. Not sure when it quit as I don't use it a lot. I'm pretty sure java was probably upgraded since I'm now at 18.04.1lts. But I've also upgraded my kernel to 4.18.7 to run on my new cpu. I've downloaded rm 2.06 build9 and upgraded rm to try and get it to work, but no go. Anyway, here's what's happening when run from terminal.

And parts of rmaster.err. weird it shows build 7?

and the end...

This was run without a jp1 cable installed. Do I now have to have it installed to run?

This appears to be the next chapter of this.

To me it just looks like a broken Java installation. Maybe some bug specific to Xubuntu 18.04.

Line 5202 in RemoteMaster class calls Toolkit.getDefaultToolkit(). This causes an exception.

A quick Google search gave me this link:

--edit--

Something occurred to me after sending this post. Which Java package do you have installed? Maybe you've only installed the headless version, which doesn't support GUI at all. You need to be sure to install full Java runtime.

It's the same java I always had installed when it worked before. It was probably updated, but other than that I hadn't removed it or added one.

Here's the original thread from June, this year.
http://www.hifi-remote.com/forums/viewt ... p?t=101290

And this was the version running then. So it did get updated, as did everyones that ran software updater. And I'm sure it will probably be updated again in the future.

That doesn't change the fact that a cause of the issue in your case is bad java installation. The error comes from the java itself, not from the rmir code not being compatible with something.

I'd suggest uninstalling whatever java package you have installed and install either openjdk-8-jre or openjdk-8-jdk package.

No, I don't have a "bad" java installation. Just a newer version.Yes, I know it works with java 8. That's not the point. Are you saying that RM just isn't designed to work with newer Java versions, and in the future never will be? Thought I was being helpful pointing this out. Guess not.

It works with both Java 9 and 10 since my changes in 2.06 build 8. I've just downloaded the latest build 9 (from RMIR thread) and I have no problem running it on Java 10.0.2 on my Arch Linux:

Code: Select all

% java -version                                      
java version "10.0.2" 2018-07-17
Java(TM) SE Runtime Environment 18.3 (build 10.0.2+13)
Java HotSpot(TM) 64-Bit Server VM 18.3 (build 10.0.2+13, mixed mode)

Like I've said, the exception in the stack trace you've posted comes from the Java itself, not RMIR code. This shows that your Java installation is missing some crucial component. Maybe it's a bug in openjdk-11-* packages in (X)ubuntu 18.04 (yes, Java 10 in Ubuntu 18.04 comes from openjdk-11-* packages, which is weird).
The exact error is

Code: Select all

Exception in thread "main" java.awt.AWTError: Assistive Technology not found: org.GNOME.Accessibility.AtkWrapper

so maybe you need to install some gnome libraries.

And please try doing the steps from the askubuntu forum I've posted above. I know it's for older Ubuntu/Java versions, but maybe it's still relevant.
