Hi Patrick,
thanks for you answer.
I tried to debug (not that easy) that and it seems to me that not the
OS.g_main_context_iteration is stuck but the readAndDispatch method is
called constantly because there seem to be events to be processed.
(I'll try to validate that tomorrow with another remote debug setup)
Is that the reason the SWTBot thread does not get the UI lock?
I was not able to identify any events from that loop.
Is there anything else I can provide or try?
Best Regards,
Peter
BTW: I noticed i probably should have posted that question in the forum
instead on the dev list. Sorry about that.
Should i move my request to the forum?
Gtk-WARNING **: Allocating size to GtkScrolledWindow 0x7fca5cec50d0
without calling gtk_widget_get_preferred_width/height(). How does the
code know the size to allocate?
Gtk-WARNING **: Negative content width -9 (allocation 4, extents 6x7)
while allocating gadget (node separator, owner GtkSeparatorToolItem)

Hi Peter,
Are you able to reproduce this while debugging? I am curious to know
if OS.g_main_context_iteration() is stuck or if the readAndDIspatch()
loop is executing constantly.
At first glance it looks like the main thread is stuck and SWTBot is
just waiting for the display thread to be available.
I have seen in the past some examples of GTK freezing the UI (for
example https://bugs.eclipse.org/bugs/show_bug.cgi?id=532340
<https://eur02.safelinks.protection.outlook.com/?url=https%3A%2F%2Fbugs.eclipse.org%2Fbugs%2Fshow_bug.cgi%3Fid%3D532340&data=04%7C01%7C%7Ccfc942484d9440ff695208d9066730f1%7C48837bc476f9481d8a76bd7b60b43dec%7C0%7C0%7C637550135981146443%7CUnknown%7CTWFpbGZsb3d8eyJWIjoiMC4wLjAwMDAiLCJQIjoiV2luMzIiLCJBTiI6Ik1haWwiLCJXVCI6Mn0%3D%7C1000&sdata=vyWOFGALEDMjEU6WDIHSlLM3fAwsyZ5V9uv8ahMdPSw%3D&reserved=0>)
but it was usually with older versions. Your GTK version seems recent
enough.

Hi everyone,
we are in the process of migrating our RCP based product from Eclipse
Mars to 2020-12.
Which indirectly also means updating to Java 11 and GTK3( for
SWTBot tests).
After migration we face the issue that at some point the test
execution
get's stuck. (but always at the same test(s))
A thread dump shows that the SWTBot Testable thread get's stuck
waiting
for the UI thread.

I can't see what's causing the issue here. Any idea's or hints are
more
than welcome!
