Description Christian Stadelmann 2015-12-11 13:02:06 UTC 
Description of problem:
I ran eclipse in a Gnome+Wayland session, so it was running with SWT+Gtk3+Wayland backend. When right-clicking on one of the perspectives, eclipse crashes.

Version-Release number of selected component:
java-1.8.0-openjdk-headless-1.8.0.65-4.b17.fc23

Comment 9 Christian Stadelmann 2015-12-11 13:20:35 UTC 
Probably an issue in Eclipse or Gtk3.

Software versions:
eclipse-platform-4.5.1-6.fc23.x86_64
eclipse-swt-4.5.1-6.fc23.x86_64
gtk3-3.18.6-1.fc23.x86_64
glib2-2.46.2-1.fc23.x86_64
xorg-x11-server-Xwayland-1.18.0-2.fc23.x86_64
Comment 10 Kamil Páral 2015-12-15 09:46:40 UTC 
Hi Christian, can you reproduce this reliably? Does the same crash occur when running under X11 or not? Thanks.
Comment 11 Christian Stadelmann 2015-12-15 17:44:40 UTC 
This crash does not happen when running under X11 (or under XWayland with GDK_BACKEND=x11 set), only on wayland (with wayland backend for Gtk+ 3.x). With X11 backend I am running into this issue instead: https://bugzilla.redhat.com/show_bug.cgi?id=1290791

Yes, I can reproduce this reliably. Steps to reproduce:
1. open eclipse with gtk3 in a wayland session. Gtk3 should choose wayland as its backend by default. Select a workspace if required
2. open any perspective
3. right-click on the perspective (right top corner of eclipse main window)

What happens:
Instant crash.

Note: you might have trouble right-clicking on the perspective button due to https://bugzilla.redhat.com/show_bug.cgi?id=1255007 . I have to click ~20…50 pixels above the button to hit it.
Comment 12 Christian Stadelmann 2016-05-06 16:31:48 UTC 
Still present with eclipse-swt-4.6.0-0.5.git201604261105.fc24.x86_64 on Wayland. Same reproducer as in comment #11.
Comment 13 Christian Stadelmann 2016-09-01 11:58:08 UTC 
This bug now (in F25) triggers a crash in gnome-shell, see bug #1330510 and bug #1372311 for details.
Comment 14 Matthias Clasen 2016-09-06 18:36:48 UTC 
If this is reproducible, you could try to break on display_protocol_error where the EPROTO originates.

Same on F24 too.

Yes, see attached logs. Steps I did:
0. run gdb from outside your gnome+wayland session, otherwise it will be killed when your session goes down.
1. start eclipse in a gnome+wayland session (and make sure it is running with wayland backend)
2. attach gdb to eclipse's child process named "java"
3. gdb: enable logging
4. gdb: disable handling of SIGSEGV because java is crazy and uses SIGSEGV for normal operation: `handle SIGSEGV nostop noprint`
5. gdb: `break display_protocol_error`
6. gdb: continue
7. eclipse: right-click on any perspective button
8. gdb: `bt` and `t a a bt full`, then continue to the next hit. In fact I ran these commands 3 times, the last one probably contains an error that the wayland compositor is gone.
9. quit gdb, recover your gnome wayland session

When trying again to reproduce, eclipse crashes. This time with a more meaningful crasher reporting a stackoverflow. See attached logs for details.
Comment 17 Christian Stadelmann 2016-09-28 20:28:02 UTC 
This issue is gone now on Fedora 25 with latest updates installed.
