Dear Maintainer,

After an unattended update the Eclipse IDE (2026-06 and 2026-09) almost
immediately crashes after one starts working with it.

The offending update was

Start-Date: 2026-10-02 08:17:04
Commandline: /usr/bin/unattended-upgrade Upgrade:
  libjavascriptcoregtk-4.1-0:amd64 (2.52.6-1~deb13u1, 2.54.0-1~deb13u1),
  libwebkit2gtk-4.1-0:amd64 (2.52.6-1~deb13u1, 2.54.0-1~deb13u1)
End-Date: 2026-10-02 08:17:09


A downgrade with

apt install --allow-downgrades \
   libjavascriptcoregtk-4.1-0=2.52.6-1~deb13u1 \
   libwebkit2gtk-4.1-0=2.52.6-1~deb13u1

resolves the issue.

I believe that Eclipse uses WebKit to display context information such as
available methods or documentation, causing the crash.

Thanks for the report, do you have the $PULSE_SERVER variable set by
any chance?

This could be the same as bug #1149690

We have identified a problem and we're fixing it as soon as possible.

This is WebKit bug 322394 — a regression from 317619@main, which made
WebKit require the process's OS main thread to be the first to call
initializeMainThread(). SWT initializes WebKit from the GTK UI thread
the JVM creates, so the RELEASE_ASSERT in MainThread.cpp:47 always fails.

Reverted upstream in 321625@main. Fedora shipped it downstream as
webkitgtk-2.54.0-2.fc45 rather than waiting for 2.54.1, which fixed
Eclipse there while keeping the 2.54.0 security fixes.

I've done some more research and found this possibly related bug:

Hello,

I have prepared a test build with fixes for #1149690 and #1149700.

I would appreciate if you could test it and verify that it fixes the
problem for you.

You can download the packages here:

https://people.debian.org/~berto/webkit2gtk-2.54.0/trixie-amd64/

Of course you don't need to install all of them, only the ones that
you already have :-)

The sha256sums file contains the checksums of all files and is signed
by me, so you can verify the authenticity if you have the
debian-keyring package installed:

gpg --keyring /usr/share/keyrings/debian-keyring.gpg --verify sha256sums.asc

Thanks!

I was able to reproduce both bugs and confirm that the fixes work. I
just released WebKitGTK 2.54.0-1~deb13u2 with the fixes.
