PhantomJS integration with ReadyAPI v3.9.1

Hi,

We have just recently migrated from ReadyAPI v2.6.0 to v3.9.1. 

We had PhantomJS integrated with Selenium Standalone jars to test few headless browsers. This sis till working all right for v2.6.0 but it's failing with v3.9.1. Smartbear suggested that with the upgraded Java libraries, PhantomJS will not work anymore.

Any suggestions please in terms what other headless browser testing options we can utilize instead of PhantomJS in ReadyAPI. Any pointers are appreciated.

Regards,

Arup
