New Features and Changes
Protections Against Unauthorized Redistribution of Java Applications
Starting with 7u45, application developers can specify new JAR manifest file attributes:
Application-Name: This attribute provides a secure title for your RIA.
- JAR is signed by a trusted CA, has the
Application-Library-Allowable-Codebase: If the JNLP file or HTML page is in a different location than the JAR file, the Application-Library-Allowable-Codebase attribute identifies the locations from which your RIA can be expected to be started.
If the attribute is not present or if the attribute and location do not match, then the location of the JNLP file or HTML page is displayed in the security prompt shown to the user.
Note that the RIA can still be started in any of the above cases.
Developers can refer to JAR File Manifest Attributes for more information.
Restore Security Prompts
A new button is available in the Java Control Panel (JCP) to clear previously remembered trust decisions. A trust decision occurs when the user has selected the Do not show this again option in a security prompt. To show 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.
Starting from JDK 7u45, the following new processing limits are added to the JAXP
For more information, see the new Processing Limits lesson in the JAXP Tutorial.
The java.util.TimeZone.setDefault(TimeZone) method has been changed to throw aSecurityException if the method is called by any code with which the security manager'scheckPermission call denies PropertyPermission("user.timezone", "write"). The new system property jdk.util.TimeZone.allowSetDefault (a boolean) is provided so that the compatible behavior can be enabled. The property will be evaluated only once when thejava.util.TimeZone class is loaded and initialized.
This release contains fixes for security vulnerabilities. For more information, see Oracle Critical Patch Update Advisory.
You can work around this using one of the following approaches:
- Sign the JAR files. (Self signed can cause the LiveConnect dialog to show already; or add a manifest file that specifies the Caller-Allowable-Codebase attribute.)
- Use the Deployment Rule Set (DRS) to allow the app and HTML to run without a warning.
Synopsis: Using the family CLSID to trigger loading of an applet does not work with certain JRE family versions.
If you use the family CLSID to trigger loading of an applet with a certain JRE family version, the family CLISD will be ignored and the latest JRE version installed on your system is used to load the applet instead. Family CLSID is specific to Internet Explorer. The workaround is to use thejava_version applet parameter or the version attribute of the Java element in JNLP file instead.
Synopsis: Certificate-based DRS rule does not work when main JAR is in nested resource block
The certificate-based Deployment Rule Set rule does not work properly for JNLP applications when the main JNLP file has no JAR files, or all JAR files are in nested resource blocks nested in<java> or <j2se> elements.
Synopsis: Caller-Allowable-Codebase may be ignored when used with Trusted-Library.
Synopsis: Applet could fail to load by throwing NPE if pack compression is used with deployment caching disabled.
If a JAR file is using pack compression with manifest entries Permissions and Caller-Allowable-Codebase while deployment caching is disabled, then:
- The Permissions manifest entry will be ignored. (This can be seen from the fact that yellow warning is there on security dialog even though the Permissions attribute is there.) This only happens if Caller-Allowable-Codebase attribute is present along with the Permissionsattribute.
- The Caller-Allowable-Codebase attribute will cause the applet to fail to load by throwing ajava.lang.NullPointerException.
If you want to use pack compression with the Caller-Allowable-Codebase attribute, there are two possible workarounds:
- Enable caching and all issues listed will disappear.
- Do not use the pack property jnlp.packEnabled=true while deploying the applets usingCaller-Allowable-Codebase and premissions property. Instead use the ContentTypeservlet for serving the pack files.
Synopsis: Non-JNLP trusted applet fails to load using the file:\\ URL.
Local trusted applets that do not deploy using a JNLP file will fail to load by throwing ajava.lang.NullPointerException. You can work around this issue by using one of the following methods:
- Use a JNLP file to launch the applet.
- Try loading the applet over HTTP or HTTPS.
Synopsis: JNLP applet fails to load if using JNLP versioning.
Due to this bug, if you are using the jnlp.versionEnabled property for JAR versioning in your browser applet, your applet might not start. Also users might see a yellow warning about a missingPermissions attribute in the following two scenarios:
- The jnlp.versionEnabled property is set to false inside the JNLP file and the version is defined against the main JAR file.
- You use JNLPDownloadServlet for version download support.
The workaround is to either not use versioning via jnlp.versionEnabled, or to use theJNLPDownloadServlet servlet for version support instead.
