With regular webkit the stack trace looks like this: 1 .. /lib64/libjavascriptcoregtk-4.0.so.18(WTFCrash+0x.. 2 .. /lib64/libwebkit2gtk-4.0.so.37(+0x... 3 .. /lib64/libwebkit2gtk-4.0.so.37(+0x... 4 .. /lib64/libwebkit2gtk-4.0.so.37(+0x... 5 .. /lib64/libwebkit2gtk-4.0.so.37(+0x... 6 .. /lib64/libgobject-2.0.so.0(g_object_unref... 7 .. /lib64/libc.so.6(+0x3ac18) 8 .. /lib64/libc.so.6(+0x3ac6a) 9 .. /lib64/libc.so.6(__libc_start_main+0xf1) 10 .. /usr/lib/jvm/java-1.8.0-openjdk-1.8.0.131-7.b12.fc26.x86_64/bin/java # .. # SIGSEGV (0xb) at pc=0x00007f2c7cea3efc, pid=16754, tid=0x00007f2cfc6d9700 # .. # JRE version: OpenJDK Runtime Environment (8.0_131-b12) (build 1.8.0_131-b12) # Java VM: OpenJDK 64-Bit Server VM (25.131-b12 mixed mode linux-amd64 compressed oops) # Problematic frame: # C [libjavascriptcoregtk-4.0.so.18+0xd76efc] WTFCrash+0x1c # .. # /home/lufimtse/git/eclipse.platform.swt/examples/org.eclipse.swt.snippets/hs_err_pid16754.log There are also some hints about webkit wanting to call a java method, which cannot be found.. not sure if relevant... > > > (gdb) bt > > #0 WTFCrash() () at Source/WTF/wtf/Assertions.cpp:278 > > #1 WebKit::CallbackMap::invalidate(WebKit::CallbackBase::Error) > > (error=WebKit::CallbackBase::Error::OwnerWasInvalidated) > /WebKit/UIProcess/GenericCallback.h:225 > > #2 WebKit::WebCookieManagerProxy::processPoolDestroyed() > /WebKit/UIProcess/WebCookieManagerProxy.cpp:76 > > #3 WebKit::WebProcessPool::~WebProcessPool() __in_chrg=.. > /Source/WebKit/UIProcess/WebProcessPool.cpp:298 > > #4 WebKit::WebProcessPool::~WebProcessPool() WebKit/UIProcess/ > WebProcessPool.cpp:317 > > #5 WTF::ThreadSafeRefCounted<API::Object>::deref() const .. > WTF/wtf/ThreadSafeRefCounted.h:71 > > #6 WTF::derefIfNotNull<WebKit::WebProcessPool>(WebKit:: > WebProcessPool*)(ptr=../WTF/wtf/RefPtr.h:45 > > #7 WTF::RefPtr<WebKit::WebProcessPool>::~RefPtr() __in_chrg=.. > /WTF/wtf/RefPtr.h:69 > > #8 _WebKitWebContextPrivate::~_WebKitWebContextPrivate() __in_chrg=. > /WebKit/UIProcess/API/glib/WebKitWebContext.cpp:163 > > #9 webkit_web_context_finalize(GObject*) (object=... > /WebKit/UIProcess/API/glib/WebKitWebContext.cpp:245 > > #10 g_object_unref (_object=0x7fde296e7110) at gobject.c:3185 > > #11 __run_exit_handlers (status=0, listp=0x7.... <__exit_funcs>, > run_list_atexit=run_list_atexit@entry=true, run_dtors=run_dtors@entry=true) > at exit.c:83 > > #12 __GI_exit (status=<optimized out>) at exit.c:105 > > #13 __libc_start_main (main=0x151b63e670 <main>, argc=5, > argv=0x7ffc1db781f8, init=<optimized out>, fini=<optimized out>, > rtld_fini=<optimized out>, stack_end=0x7ffc1db781e8) > > at ../csu/libc-start.c:329 > > #14in _start () > > ... > > 1 /lib64/libjavascriptcoregtk-4.0.so.18 WTFCrash > > 2 /lib64/libwebkit2gtk-4.0.so.37 > > ..6 /lib64/libgobject-2.0.so.0(g_object_unref..) > > ..9 /lib64/libc.so.6(__libc_start_main..) > > ..10 /usr/lib/jvm/java-1.8.0-openjdk-1.8.0.131-7.b12.fc26. > x86_64/bin/java > > > > I noticed that if I do an g_object_ref(webview) somewhere near disposal, > then the crash doesn't occur.
