This seems not a general problem but related to certain elements. To test, put a breakpoint afgter CTabFolder line 2808 (ToolBar chevron = getChevron();) and try to see chevron in the Variable viewl

Most likely you can't do this for all things running in UI thread, right? If so, this is because SWT has thread checks which do no tallow other threads to mess up with widgets.

I have a hard time parsing that comment. I'm using the "Variables" view in the debugger. The display of this view always happens in the main thread. Also the code I'm debugging is in the main thread.
Comment 4 Andrey Loskutov CLA 2018-02-20 11:52:58 EST 
The code evaluation in the debuggee is executed not in UI thread, but you most likely want to access something which can be accessed from UI thread only => exception. I wonder if the error log view doesn't show the original exception?

This bug hasn't had any activity in quite some time. Maybe the problem got resolved, was a duplicate of something else, or became less pressing for some reason - or maybe it's still relevant but just hasn't been looked at yet.

If you have further information on the current state of the bug, please add it. The information can be, for example, that the problem still occurs, that you still want the feature, that more information is needed, or that the bug is (for whatever reason) no longer relevant.
