Locked Java exception when starting JMRI 4.20 with Java 17

 

Hello all,
?
I'm trying to get JMRI 4.20 running on a Raspberry 3b.? The RPi OS came with Java 17.0.14.? I'm wondering if JMRI 4.20 will even run with that version of Java.? If not I'll need to upgrade to the latest 5.x version of JMRI.? Thanks and take care.

If you’re starting from scratch I’d STRONGLY suggest looking at Steve Todd’s images for Ras Pis

They take all the guesswork away

See?

Dennis,

A quick test indicates the 4.22 might work with Java 17. ?4.26 definitely works with Java 17. ?

Then again, maybe this a good opportunity to get current.

Hello Dave and all,

Great progress has been made.? I have updated JMRI to 4.26 and everything works except...? No messages in the error log.? I can successfully?load a panel and initialize?it.? The missing track lines that I had before are now fixed, how I don't know.? But now, as soon as I try to open a turnout or sensor table I get the message in the attached image.? So close and yet so far.? Thanks?again for all your assistance.

Is there a reason you have not updated to at least the latest production version of JMRI? 4.20 was almost 5 years old, 4.26 is over 3 years old.

I wouldn't expect support for such outdated versions.

Hi Peter,

I support systems running 3.10, 4.20 and 4.26.? I don't see the need to upgrade to the latest unless it's necessary, but if need be I will.? Thanks and take care.

Dennis,

When you use Tools -> Tables -> ????, all of the tables are initialized. ?In this case, the Audio table has a problem.

When you installed JMRI 4.26 did you delete or rename the existing JMRI directory before expanding the download?

The reference to "/home/sci/JMRI/libgluegen-rt.so" is wrong. ?The actual path is "/home/sci/JMRI/lib/linux/.../libgluegen_rt.so". ?The "..." depends on the PC hardware.

If you start PanelPro from the command line with the -d option, the log directory will have the launcher.log file. ?That might have some clues.

cd ~/JMRI
./PanelPro -d

An interesting test would be to add the bell sounds and see if the problem returns.

All,

I think there are more than anyone is willing to admit still running JMRI 4.26.
?
Uninstalling and upgrading your JAVA is just the beginning of PITAs involved (not to even mention Windows versions needed and its hardware requirements), and no one has ever given a single, solitary example of some extra, additional, or improved feature that a later JAVA version has. I've asked before. Of course, if anyone can offer anything like that now, then knock yourself out. That would contribute to the discussion.
?
Regards
 

Don,

For new and improved features, the releasenotes are the place to look. Also, there is no shame in being happy with an older release. Having said that, it's nobody's task to convince people one way or the other. It's everyone's own choice to update, not to update, when to update, which version(s) to update to. One thing that will become increasingly important, is that if support is necessary, the older the version, the less likely people iving support are going to be willing to invest their precious time to investigate. That's probably the biggest risk involved.

Adding to Wouter, the further “behind” you get from current, the bigger the task (and risks) there will be if/when you DO need to upgrade?

My oldest environment is running Windows 8 (still) and I really can’t remember the last time I hit a problem when upgrading. All my JMRIs are current

Don,

For new and improved features, the releasenotes are the place to look. Also, there is no shame in being happy with an older release. Having said that, it's nobody's task to convince people one way or the other. It's everyone's own choice to update, not to update, when to update, which version(s) to update to. One thing that will become increasingly important, is that if support is necessary, the older the version, the less likely people iving support are going to be willing to invest their precious time to investigate. That's probably the biggest risk involved.

Uninstalling and upgrading your JAVA is just the beginning of PITAs involved (not to even mention Windows versions needed and its hardware requirements), and no one has ever given a single, solitary example of some extra, additional, or improved feature that a later JAVA version has. I've asked before. Of course, if anyone can offer anything like that now, then knock yourself out. That would contribute to the discussion.

I agree.

Another test could be to run the script AudioExample.py. The JMRI System Console output would probably give a hint.

Thank you in advance.

Wouter is not the first to conflate "some extra, additional, or improved feature" of JAVA itself, with those of JMRI. The latter is certainly documented, but it is the former which I challenge. What later JAVA improvements enabled or improved JMRI code?
?
And the "precious time" argument is always laid bare when coders spend it denying bugs rather than fixing them.

The JAVA debate is certainly separate from the JMRI one

Unfortunately, JMRI does not control the release cycles of JAVA, but generally any a that are taken advantage of tend to make coding simpler and more efficient with no obvious external benefits. So I think we agree there

As for denying the existence of bugs - I have to disagree

JMRI has fixed at least four issues for me in the last 12 months alone

And you’ve been answered before:

Don,

I did nothing of the kind.
