Problem
Captcha Image is failed to load in the Browser UI and hence resulting in a user unable to login. Captcha is shown when a user has made too many failed login attempts.

Caused by: org.springframework.beans.BeanInstantiationException: Failed to instantiate [com.octo.captcha.engine.image.gimpy.DefaultGimpyEngine]: Constructor threw exception; nested exception is java.lang.NoClassDefFoundError: Could not initialize class sun.awt.X11GraphicsEnvironmentCause
The following could be the possible causes:
Unsupported JDK.
The server is headless which means that there is no graphics environment to load the captcha service.
Workaround
Disable the Captcha Verification and then try to log in.
Steps:
Stop Bamboo
Edit the "<bamboo_home>/xml-data/configuration/administration.xml" file and you will see a block:
1 2 3 4 5<captchaConfiguration> <enableCaptcha>true</enableCaptcha> <enableCaptchaOnSignup>true</enableCaptchaOnSignup> <maxLoginAttempts>3</maxLoginAttempts> </captchaConfiguration>Change it to:
1 2 3 4 5<captchaConfiguration> <enableCaptcha>false</enableCaptcha> <enableCaptchaOnSignup>true</enableCaptchaOnSignup> <maxLoginAttempts>3</maxLoginAttempts> </captchaConfiguration>Restart Bamboo and try to login again.
Resolution
Check and confirm if you are using the correct Java Version as per your Bamboo Version. See this for more info - Bamboo Supported Platforms
Verify from your system information page whether you have this environment variable set:
1-Djava.awt.headless=true
