Workshop basics blank screen in eclipse SDK
FreeBSD-12.1p10
Eclipse install and runs. However, when any of the instruction topics
(Workbench basics, Java development, Eclipse plug-in development) are opened
all that displays ia blank grey window with what appears to be a progress bar
in the lower right which does not show any activity.
Steps to reproduce:
1. Open eclipse, Welcome window displays.
2. From Welcome window select Workbench basics.
3. Results expected - Workbench basics window opens with text.
4. Results observed - Empty window opens, see attachment.
When run from CLI the following is recorded:

SWT call to Webkit timed out after 100ms. No return value will be provided.
Possible reasons:
1) Problem: Your javascript needs more than 100ms to execute.
Solution: Don't run such javascript, it blocks Eclipse's UI. SWT currently
allows such code to complete, but this error is thrown
and the return value of execute()/evalute() will be false/null.
2) However, if you believe that your application should execute as expected (in
under100 ms),
then it might be a deadlock in SWT/Browser/webkit2 logic.
I.e, it might be a bug in SWT (e.g this does not occur on Windows/Cocoa, but
occurs on Linux). If you believe it to be a bug in SWT, then
