Release 2.6.0 ...

FYI, updated the -rc into a distribution of JaamSim and at least on Windows x86-64 everything worked as expected so far.

Harvey

Thank you and good to know it works so far.

Thanks a lot for this release candidate !

For now i don't see any issue on our side for Linux with JOGL part with latest rc (I must package a version for other os)

For JOAL part the only issue i have see for now is a charset issue on alcGetString & alcGetStringAsDoubleNullTerminatedString on my linux host (The charset is decoded with  "US-ASCII" but openal-soft seems return strings with UTF-8 charset), i fill a bugzilla ticket for this issue

Second RC from 20250706:
<https://jogamp.org/deployment/v2.6.0-rc-20250706/> 

Moved to Doxygen Javadoc for all modules, notable
- GlueGen https://jogamp.org/deployment/jogamp-next/javadoc/gluegen/javadoc/
- JOGL https://jogamp.org/deployment/jogamp-next/javadoc/jogl/javadoc/index.html

Motivation:
- Forced to use Java-17 (due to SWT) on 'javadoc node'.
- javadoc is barely acceptable since java > 11 IMHO
- can use markdown docs and markdown documentation style
- all sort of OO and calltree svg creations

Besides, some features and mild fixes since last RC build - otherwise no change.

IMHO almost sort of ready to be released.

Great .. and yes, please do so (joal bug) - not seeing you in here yet
https://jogamp.org/bugzilla/buglist.cgi?chfield=%5BBug%20creation%5D&chfieldfrom=7d&list_id=3205

I finally merged your GlueGen manual changes, hope the move to Doxygen pleases all.
Yes, I use a manually tinkered doxygen-awesome.css I also used in my 'jaulib' C++/Java project and others.

Yeah thanks a lot for merging the changes of gluegen manual !

JOAL bug filled (sorry for the delay, deadline at work last week i didn't find the time for the report :x) : https://jogamp.org/bugzilla/show_bug.cgi?id=1517

And yeah the javadoc with doxygen look really nice!

perfect, thank you.

Yes, I just did my quick bring up tests w/ GraphUI + ffmpeg + JOAL, hearing the sound was enough for me, didn't check all the print dumps :)

Perhaps this is a chance to make a unit test for these? 'OpenAL Soft' (or similar) at least should be visible somewhere now.

Doxygen: Yes, I was so frustrated about 'new' javadoc, ruining all the documentation work, I moved to doxygen a while ago for other projects. Finally adopted it here.
It also shows the source code for all demos and unit-tests and one can hover or click on all API entries.
So it is also a great way to independently learn the API itself.

GraphUI demos:
- classes: https://jogamp.org/deployment/jogamp-next/javadoc/jogl/javadoc/namespacecom_1_1jogamp_1_1opengl_1_1demos_1_1graph_1_1ui.html
- UISceneDemo03 source: https://jogamp.org/deployment/jogamp-next/javadoc/jogl/javadoc/UISceneDemo03_8java_source.html

I've put out a release of jaamsim updating to the second jogl release candidate, already had success reports for:

Win 10 x86-64, OpenJDK 21
Ubuntu 24.04.2 LTS x86-64 with OpenJDK 21

I'll collect any further reports for end of week, or sooner if any problems arise.

For now i don't see any issue on our side on following hosts with latest RC (06/07/25) of JOGL :
 * Fedora Linux 42 x86_64 (Nvidia card with nouveau driver of Mesa)
 * Windows 10 x86_64 (one with Intel card & another with Nvidia card)
 * Windows 11 x86_64 (one with Nvidia card & another with AMD card)
 * MacOS High Sierra 10.13.6 x86_64
 * MacOS Monterey 12.7.4 x86_64

We can, for our case with OpenAL-soft we can query following alc strings :
 ALC_DEFAULT_DEVICE_SPECIFIER, ALC_DEVICE_SPECIFIER, they seems always return "OpenAL Soft\0" since this commit (For 1.14 release in 2012) : e2ccc6f98e63dc2ba74e2c989be3fc899602848d (Always use "OpenAL Soft" for the short device enumeration list - 21/02/12)

No issues to report from Jaamsim users, have had a few dozen downloads of the -rc2 and -rc3 JOGL test versions.

One interesting report was from a successful test on ChromeOS, I'm trying to gather some more information on how exactly that deployment happened because I honestly never even thought to try it there. Anyone else deploying JOGL applications on ChromeOS?

Harvey

Nope. I just fiddled a lot with re-enabling Android again *phew*.
Conclusion: Our source must stay in the Java8 compatible API realm,
until until using a minimum of Android API 32 (Version 12).
Today, this would drop a lot of devices .. purely academical ofc :)
<https://jogamp.org/bugzilla//show_bug.cgi?id=1520#c4>

Hence .. will probably see to use the '--release 8' of 'javac'
to ensure API Java8 compatibility.

Also dropped the native '-android' jar polution (next RC).

Will the return to a release 8 happen in the next release candidate or has it already been included in the current one? I'll make sure to put out a test version of jaamsim to re-enable the java 8 compatibility for testing when it's available.

Thanks again for all your efforts.

Harvey

looks like .. yes.

Working on using the (new) javac '--release 8' option
until we move over to Java11 completely - if ever :)

Yes, was too optimistic about Java 11 Android support,
but the desugar and adding/copying certain Java-11 libs is too expensive.
At least Android API 26 supports all our used Java8 API entries.

Java8:

- https://jogamp.org/gluegen/doc/JogAmpPlatforms.html

Next RC will be back to 'normal' :)

Harvey et al., my apologies for causing this Java 8 compatibility confusion (or chaos).

Next time when considering inconvenient compatibility runtime changes as such, I will ask beforehand.

Potential departure from Java 8 compatibility may occur in the future,
but it probably will take a few years until most of its dependencies become irrelevant.

What is left for 2.6.0?
- Bug 1444 <https://jogamp.org/bugzilla//show_bug.cgi?id=1444>

See 2.6.0 wiki <https://jogamp.org/wiki/index.php?title=SW_Tracking_Report_Objectives_for_the_release_2.6.0>

Eyeballing end of August '25 for the release.
