Version History of Java 7 Update 51
Security Feature Enhancements
- Changes to Security Slider
- Block Self-Signed and Unsigned applets on High Security Setting
- Require Permissions Attribute for High Security Setting
- Warn users of missing Permissions Attributes for Medium Security Setting
- Restore Security Prompts - Clear Remembered Trust Decisions
- In Java 7u51, users are given an option to restore the security prompts for any prompts that were hidden prior to installing the latest release. It is recommended that users restore security prompts every 30 days to ensure better protection.
- A trust decision occurs when the user has selected the Do not show this again option in a security prompt. To show the prompts that were previously hidden, click Restore Security Prompts. When asked to confirm the selection, click Restore All. The next time an application is started, the security prompt for that application is shown. See Restore Security Prompts under the Security section of the Java Control Panel.
- Exception Site List
- The Exception Site List feature allows end users to run Java applets and Java Web Start applications (also known as Rich Internet Applications) that do not meet the latest security requirements. Rich Internet Applications that are hosted on a site in the exception site list are allowed to run with the applicable security prompts. See the Exception Site List FAQ for more information.
- Update jarsigner to encourage timestamping
- Timestamping for a signed jar is now strongly recommended. The Jarsigner tool will print out an informational warning at signing or verifying when timestamp is missing. For more information see Signing JAR Files.
- Bug Fix: Clarify jar verifications. The jarsigner tool prints out more messages when there are severe warnings and -strict is on. Read the tooldoc(link) for details.
Java Expiration Date
- The expiration date for 7u51 is April 15, 2014. For systems unable to reach the Oracle Servers, a secondary mechanism expires this JRE (version 7u51) on May 15, 2014. After either condition is met (new release becoming available or expiration date reached), Java will provide additional warnings and reminders to users to update to the newer version.
