Oracle has released Java 7 Update 21 and Java 6 Update 45. Both JDK versions have been updated in the WebUpd8 Java PPA.

Oracle JDK 7u21 changes:

  • Blacklisted Jars and Certificates: Oracle now manages a certificate and jar blacklist repository. This data is updated on client computers daily on the first execution of a Java applet or web start application
  • Changes to Java Control Panel’s Security Settings: In this release, low and custom settings are removed from the Java Control Panel(JCP)’s Security Slider
  • Changes to Security Dialogs: As of JDK 7u21, JavaScript code that calls code within a privileged applet is treated as mixed code and warning dialogs are raised if the signed JAR files are not tagged with the Trusted-Library attribute
  • Changes to RMI: From this release, the RMI property java.rmi.server.useCodebaseOnly is set to true by default. In previous releases the default value was false
  • Server JRE: A new Server JRE package, with tools commonly required for server deployments but without the Java plug-in, auto-update or installer found in the regular JRE package, is available starting from this release
  • Fixes for security vulnerabilities
