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
