Hmm, did you check-out latest branch of https://github.com/alkacon/modules-v8 and compile jars and module with Java 8 ?

Best regards,
Tobias

Hello All,
 We have both V8 and plain versions of WebForms installed. Everything is working fine except Captcha. For Captcha no image is being generated and opencms is throwing following exception:

Please note that Jcaptcha jar is available and I am using JRE-8. What can be the possible problem and how can I get it solved ... Any suggestions?
