Hello, We are pushing out a security update for java tonight. We are only going from java 1.6.0-10 to 1.6.0-12, so there isn't to much of a problem with incompatibilities. But there are some people who have several version's of sun's jdk installed, and when you update one, it uninstalls the rest. So if you have multiple copies of jdk installed, and you plan on keeping them, then you should exlude it in your yum cron exludes line, or on your yum.conf excludes line. To exclude jdk and java-1.6.0-sun-compat for the nightly automatic updates. Edit the file /etc/yum.d/yum.cron.excludes and append to it, all on one line. so it looks like exclude=kernel* openafs* jdk java-1.6.0-sun-compat To exclude jdk and java-1.6.0-sun-compat for all yum update. Edit the file /etc/yum.conf and add the line exclude=jdk java-1.6.0-sun-compat Hopes this helps some people. Most people won't have any problem with the update, but I just wanted to make sure for the others. One other note. We were able to sign the i586 jdk rpm, but not the x86_64 one. The x86_64 one still breaks when you sign it.
