Seeing the following error quite a few times:

SWT call to Webkit timed out after 10000ms. No return value will be provided.
Possible reasons:
1) Problem: Your javascript needs more than 10000ms 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 under10000 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

Possibly a webkit2-gtk3 based error, as other toolkits (eg: qt5) also suffer the same timeout problems.

This bug also make "java context assist" very slow.
I try to set ASYNC_EXEC_TIMEOUT_MS from 10000ms to 50ms, this make eclipse much useful.

BTW:
javadoc and internal web browser also not work.

I try to use webkit2-gtk3-2.22.6, Timeout errors is not occurred;)
