No return value will be provided. 17:05:07 Possible reasons: 17:05:07 1) Problem: Your javascript needs more than 10000ms to execute. 17:05:07 Solution: Don't run such javascript, it blocks Eclipse's UI. SWT currently allows such code to complete, but this error is thrown 17:05:07 and the return value of execute()/evalute() will be false/null. 17:05:07 17:05:07 2) However, if you believe that your application should execute as expected (in under10000 ms), 17:05:07 then it might be a deadlock in SWT/Browser/webkit2 logic. 17:05:07 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 17:05:07 Please report this issue *with steps to reproduce* via: 17:05:07
