Re: [platform-dev] Eclipse and Equinox 4.38 (2025-12) RC2 is available

[Thomas Reinhardt <thomas@xxxxxxxxxxxxx>]

Hi List,

not sure if this is the right place but I think I have discovered a bug 
on Debian 13. Eclipse crashes for me with a JVM error.

Reproduce:
 - download 4.38RC2 / Eclipse SDK
 - unpack
 - run eclipse with a new/temp workspace
 - open Window/Preferences
 - navigate to Java/Editor/Save Actions
 - check "Perform the selected actions on save"
 - check "Additional actions"
 - click on "Configure..." -> CRASH

...

21.0.9+10-Debian-1deb13u1)
# Java VM: OpenJDK 64-Bit Server VM (21.0.9+10-Debian-1deb13u1, mixed

# Problematic frame:

I tried with some other VMs too:

# Java VM: OpenJDK 64-Bit Server VM Temurin-21.0.8+9 (21.0.8+9-LTS,

# Problematic frame:

This is on Debian 13, xfce.

I tested with 4.35, 4.36 and 4.37 also. All of them crash.

Also, I did a quick test in a Win11 VM and there it does not crash. So 
maybe a GTK/SWT issue? I'm only guessing of course.
