OpenHAB designer causes crash in soup_session_feature_detach

Running OpenHAB designer through any Java VM (tried 1.7, 1.8 and Oracle 1.8), causes a crash in libsoup:

Patch for the crash

With recent versions of WebKitGTK+, Eclipse crashes whenever Javadoc hover help is to be displayed in Java editor.

Looks this happens because WebKit doesn't attach a default Authenticate listener and therefore WebKitGTK.soup_session_get_feature() returns 0 in WebKit.create(). See attached patch for fix.

Reproduced with all 3.8, 4.2 and 4.3 versions of SWT.

Grant,
Any plans to accept the patch soon? It is impossible to launch Kepler builds on Fedora 19 because of this.

[İsmail Dönmez (ismaildonmez)]

For a workaround add the following to the end of your eclipse.ini

-Dorg.eclipse.swt.browser.DefaultType=mozilla

[Akurtakov (akurtakov)]

Mozilla is even less reliable as it breaks with every firefox update ans SWT doesn't support recent xulrunner versions (20.0 here) -at least it wasn't last I checked.

[İsmail Dönmez (ismaildonmez)]

Works for me on openSUSE 12.3

[René (rkrell)]

In which environment, the same one with GNOME 3.8 (separate repository GNOME:STABLE) using libsoup 2.42.0? See also bug 405786.
Also in this report there was said "with recent versions of WebkitGTK+" (which is not a standard OpenSUSE 12.3)

(In reply to comment #8)

[İsmail Dönmez (ismaildonmez)]

Ah I am using GNOME:Stable:3.8 repo.

I use apparently (almost) the same environment OpenSUSE 12.3 + GNOME:Stable:3.8 and it crashes. Before updating to GNOME:Stable:3.8 it didn't crash for several weeks of intensive work with Eclipse. Therefore I'd rather ask:
- You don't override -Dorg.eclipse.swt.browser.DefaultType in eclipse.ini?
- Did you try the Javadoc hovers in some open Java editor for a while?

1. I have -Dorg.eclipse.swt.browser.DefaultType=mozilla in my eclipse.ini
2. Yes I did, I opened an Android project and checked docs for multiple functions. Works fine.

[René (rkrell)]

Oh Ismail, sorry, I think I got the message after I've noticed your comments above. You tried the workaround, not the standard Eclipse.
The workaround with the "mozilla" default type works for me, too, using Firefox 20 (xulrunner-17.0.5-2.1.x86_64).

A fix will be in for 4.3M7. I don't have a built WebKitGTK 2.0 to use yet, and I want to do a good test pass with it.

Just wanted you to know that adding the line to eclipse.ini seems to work for me under Ubuntu Gnome 13.04, upgraded to Gnome 3.8.1. Will the fix be part of this summer's Juno successor?

If not, I think the workaround info needs somehow to be spread, because this bug renders Eclipse totally unusable on newer Gnome-based linux distros, and this entry seems somewhat hard to find using google ... I didn't, which is the reason I created the duplicate, and I fear I won't have been the last.

[Grant Gayed (grant-gayed)]

(In reply to comment #19)
> Will the fix be part of this summer's Juno successor?

Yes, it will be in the June 4.3 release.

[Jlmoya (jlmoya)]

The workaround didn't do it for me as eclipse 4.2.2 continues to crash. Does anyone have any other suggestion as to how to fix the problem? Would anyone be kind enough to explain how to apply the patch attached?

[Grant Gayed (grant-gayed)]

(In reply to comment #21)

To work around this with 4.2.2 you need to add two lines to the end of your eclipse.ini:

1. the line in comment 6
2. -Dorg.eclipse.swt.browser.XULRunnerPath=<path> where <path> is the full path to a downloaded XULRunner to use (XULRunner 10 is suggested since it's the latest supported release). If for some reason this does not work then you can substitute an invalid path for <path> (eg.- "/dev/null"), which will run with no browser support (base eclipse runs generally fine without browser support).

Using this workaround with fedora 19 removes the crash but displays an empty information window for autocompletes (for ctrl-space); unusable.

-Dorg.eclipse.swt.browser.DefaultType=mozilla
-Dorg.eclipse.swt.browser.XULRunnerPath=/usr/lib64/xulrunner/

Thomas, do you see this problem with 4.3 final? I don't see the crash with both Eclipse from Fedora(yum install eclipse) and downloaded one from Eclipse.org. Fedora ships with xulrunner 22 which is not supported by swt.

[Thomas-skjolberg (thomas-skjolberg)]

Upgrading to 4.3 works perfectly, thanks.

[Mpol-l (mpol-l)]

The workaround seems to work on Indigo with xulrunner 17.

FWIW, the lookup/detach/attach code there is completely unnecessary anyway... The only line here that actually does anything is the g_signal_connect() line.

[Jeremiah-renfro (jeremiah-renfro)]

FWIW I found this thread because I was getting a similar crash after updating OpenSUSE to 13.1 and eclipse to Kepler (eclipse.buildId=4.3.0.M20130911-1000)

Here is the tail of the console log:

No bp log location saved, using default.
[000:000] Browser XEmbed support present: 1
[000:001] Browser toolkit is Gtk2.
[000:001] Using Gtk2 toolkit
No bp log location saved, using default.

Adding -Dorg.eclipse.swt.browser.DefaultType=mozilla to eclipse.ini seems to have resolved the problem... for now. I only think it is worth mentioning because this was supposedly resolved in 4.3

Are you sure you're seeing the same crash (the dump file from your JRE indicates that it's in the soup_session_feature_detach() call)? The fix for this was a simple null check, and I haven't heard of anyone else seeing it since the fix went in. Maybe you're seeing bug 400626?

Maybe I am experiencing 400626, thanks for pointing me there, I'll start tracking that one also.

I had the same problem in LinuxMint (petra), adding Dorg.eclipse.swt.browser.DefaultType=mozilla fixed my it. Thanks for this fix!

I can confirm that using Eclipse Luna v4.4 on Ubuntu 14.04 this doesn't happen anymore. For older Eclipse versions (e.g. 3.7.2) the -Dorg.eclipse.swt.browser.DefaultType=mozilla works for me.

Just to let you know, I use the latest Eclipse Luna releases on Ubuntu Gnome 14.04.2 (both the Java and the C/C++ flavors), and have not experienced this problem again since the Juno versions (see comment #19). Therefore, I guess there must be something special in your setup.

Mentioning this 2 years old comment, I was probably right to predict that there'd be tons of duplicates for this bug; the bug description is simply not expressive enough to find it using a standard google search ...

Please provide more details - which OS, what are the versions of GTK+ and webkit etc. and the crash logs too if possible.
