The SourceForge file area has a replacement captcha library called jcaptcha-1.0.jar; that is especially compiled for non-Oracle JVMs. Try using that instead of the one that comes in the war file.

I uploaded the jcaptcha-1.0.jar to the Tomcat bin/ directory. Changed owner, group and permission to agree with other JARs in the directory. Restart Tomcat and Restarted the OS. Same issue.

The following entries were added to logging.properties with no effect. The Tomcat logs say nothing about Captcha.

com.octo.captcha.text.level = FINE
com.octo.captcha.sound.level = FINE
com.octo.captcha.service.level = FINE
com.octo.captcha.module.level = FINE
com.octo.captcha.image.level = FINE
com.octo.captcha.engine.level = FINE
com.octo.captcha.component.level = FINE

Unless you also removed the file of the same name from the WEB-INF/lib directory, this file would be ignored. Web apps running in Tomcat load classes first from WEB-INF/lib and WEB-INF/classes, and only then from Tomcat's classpath. And no web app has access to classes from Tomcat's "bin" directory, only its "lib" directory.

moved jcaptcha-1.0.jar to .../webapps/jforum/WEB-INF/lib/jcaptcha-1.0.jar and recycled Tomcat. No effect.

Odd. Is a jforum.log file being created in the logs directory? That's where all the JForum-related logging would be directed.

The log was found in /tmp. See attached. There are Java exceptions.

I've never seen that ("word is too tall: try to use less letters, smaller font or bigger background"). The default captcha settings should work out of the box, but do a sanity check (and possibly fiddle around with) the captcha settings on the Admin Control panel -> Configurations page.

I see the earlier exceptions from using the wrong jcaptcha library are gone now, so that's progress.

Turning Captcha off then on seemed to fixed the issue. A restart of the Tomcat server was not needed. I have added three new tests ids using Captcha.
