jogl problems on mesa 20 branch

Dear community,
I am using CLC Main Worknech, which is comes with bundled jre (openjdk10) and jogl to draw 3d structures

After mesa update to 20+ branch app throws VM errors (mesa 19 and lower worked fine) on intel HD5500:

I have tried to change jre to openjdk13, replace jogl 2.12 jar files with 2.3.2 and 2.4rc but the problems persisted. As there are no other errors reported by the kernel driver, I would like to turn to jogl developers for any hints and fixes.
Thank you

Hello

I'm sorry but you'll have to ask Qiagen (the software publisher) to build CLC Main Workbench with the latest release candidate of JOGL 2.4 to make it work in your case. We don't backport bug fixes in old versions of JOGL. Maybe a few warnings will remain but they don't prevent JOGL from working with OpenJDK 14.

JOGL 2.1 and JOGL 2.4 use different package namespaces, you can't just replace JARs to make it work. Maybe you don't use the right JARs, please look at your classpath.

Hi Mato??,

if you can send me a PM, I can give you a bugzilla account
for you to describe the issue in more detail and
in a persistent manner.
See our Wiki -> Maintainer for my PM.

Below a few remarks.

So the remaining issue should be: Intel on Mesa-20+.
Have you tried using software only by setting the environment
variable LIBGL_ALWAYS_SOFTWARE
  export LIBGL_ALWAYS_SOFTWARE=true
?

If software only works, we would have an issue w/ the Mesa/Linux Intel driver
(as usual).

Best,

~Sven

Hi Sven,
you nailed it , software rendering solved the issue, which means new mesa doesnt cooperate well with any jogl release on integrated intel (i have seen many such post on this forum from the past).
I am an end user, so that why I turned to you as my java knowledge is is close to none (i can understand basic scripting).
But I am not sure is reporting this to upstream mesa will do anything. What place do you suggest to report to?
Thanks a lot
