UlteoJavaBug » History » Version 2

The current version (v2.5.1) of the Ulteo OVD server in use at [cdmeditor](http://cdmeditor.bgbm.fu-berlin.de/sessionmanager) does not seem to function correctly when accessed via browsers installed with Java plugins 1.7.xx.
Symptoms of this problem could be,
- an error message "err01 no java" instead of the "Log In" button.
- a java security error after the user has logged in succesfully logged in
- a blank white screen with no information after the user has logged in succesfully logged in
Falling back to earlier versions of the Java plugin may solve the problem, but this is not recommended due to a major security bug fix as described [here](http://blog.mozilla.org/security/2012/08/28/protecting-users-against-java-security-vulnerability/.)
The reason for the error seems to be a check in the Ulteo OVD server version v2.5.1, which rejects any Java JVM or Plugin which does not originate from the vendors 'Apple' or 'Sun Microsystems'.
