Security Baselines

The security baselines for the Java Runtime Environment (JRE) at the time of the release of JDK 8u172 are specified in the following table:

JRE Family Version JRE Security Baseline

JRE Expiration Date

The JRE expires whenever a new release with security vulnerability fixes becomes available. Critical patch updates, which contain security vulnerability fixes, are announced one year in advance on Critical Patch Updates, Security Alerts and Third Party Bulletin. This JRE (version 8u172) will expire with the release of the next critical patch update scheduled for July 17, 2018.

For systems unable to reach the Oracle Servers, a secondary mechanism expires this JRE (version 8u172) on August 17, 2018. After either condition is met (new release becoming available or expiration date reached), the JRE will provide additional warnings and reminders to users to update to the newer version. For more information, see JRE Expiration Date.

Known Issues


Description for Toolkit.getImage() and Toolkit.createImage()

The changes made under JDK-8033530 introduced an inconsistency between the implementation for and the documentation of the following methods:

  • java.awt.Toolkit.getImage(URL u)
  • java.awt.Toolkit.createimage(URL u)

The description in the API document should read:

This method first checks if there is a security manager installed. If so, the method calls the security managers checkPermission() method with the corresponding permission to ensure that the access to the image or the image creation is allowed. If the connection to the specified URL requires either URLPermission or SocketPermission, then URLPermission is used for security checks.




Touch Keyboard for Swing/AWT Text Components

This release adds support for automatically showing the touch keyboard for Swing/AWT text components on Microsoft Windows 8 or later. A user can display the touch keyboard either by using a touch screen to tap the text component area or by using a mouse to click in the area, when a keyboard is not attached to a computer.

The system property awt.touchKeyboardAutoShowIsEnabled controls whether this functionality is enabled in the JDK. This functionality is enabled by default. However, if the functionality is not needed, the user can switch it off from the command line by setting the system property to false:
