ERCaptcha with Java 1.8 shows black image only

Hi List,

has anyone running ERCaptcha with Java 1.8 successfully?

All I get is a black image when running Java 1.8 - in a project that works perfectly on my other machine with Java 1.7.

I found this on StackOverflow:

> This JCaptcha library is really old, and going by the state of their code repository, it is an abandoned project. The problem with this library is that it uses very specific version of JH Labs Image filters for CAPTCHA image distortion, and this version does not support JDK 1.8, it only supports 1.6.


(s. http://stackoverflow.com/questions/22894510/jcaptcha4struts2-plugin-image-not-loading) This may be something completely different, but it’s the best hint I found so far.

Any hint appreciated.
