How do I find out which version of Java is the system default? When you run a Java application from the command line, it uses the default JDK. If you do not develop Java applications, then you do not need to worry about this. How do I uninstall Java? If you want to continue to develop with Java 6 using command-line, then you can modify the startup script for your favorite command environment. For bash, use this:. You may need to modify those applications to find Java 6, or contact the developer for a newer version of the application.

File to what it was prior to the April CPU in which strict validity checks were not performed by default on file paths on Windows. To re-enable strict path checking in java. File, the system property jdk. This might be preferable, for example, if Windows special device paths such as NUL: are not used. This release is based on the previous CPU and does not contain any additional security fixes.
The following issues have also been resolved:. The following sections summarize changes made in all Java SE By leveraging the Kerberos cross-realm referrals enhancement introduced in the context of JDK, the 'S4U2Self' and 'S4U2Proxy' extensions may be used to impersonate user and service principals located on different realms.
New system and security properties have been added to enable users to customize the generation of PKCS 12 keystores. This includes algorithms and parameters for key protection, certificate protection, and MacData. The detailed explanation and possible values for these properties can be found in the "PKCS12 KeyStore properties" section of the java.
The following root certificates with weak bit RSA public keys have been removed from the cacerts keystore:. A new -groupname option has been added to keytool -genkeypair so that a user can specify a named group when generating a key pair. For example, keytool -genkeypair -keyalg EC -groupname secpr1 will generate an EC key pair by using the secpr1 curve. Because there might be multiple curves with the same size, using the -groupname option is preferred over the -keysize option.
It is used to indicate the certificate authorities CAs that an endpoint supports and should be used by the receiving endpoint to guide certificate selection.
This extension is always present for client certificate selection, while it is optional for server certificate selection.
Applications can enable this extension for server certificate selection by setting the jdk. The default value of the property is false. Consequently, there may be interoperability issues when jdk. As an additional way to launch processes on Linux, the jdk. The default launch mechanism VFORK on Linux is unchanged, so this additional option does not affect existing installations. The default ordered list is now:. When signing a file that contains POSIX file permission or symlink attributes, jarsigner now preserves these attributes in the newly signed file but warns that these attributes are unsigned and not protected by the signature.
The same warning is printed during the jarsigner -verify operation for such files. This change is more visible to tools like unzip where these attributes are preserved. Oracle JDK This package is provided for Solaris HarfBuzz is used directly by libraries such as Pango, and the layout engines in firefox. This is a desktop library, but the font processing it does is part of some common backend server workloads.
It should always be considered as required. If this library is missing, then the pkg mechanism will require it during installation of the JDK. If installing the JDK by using a tar. Following the JDK's update to tzdatab, the long-obsolete files named pacificnew and systemv have been removed. What is Java? What is Java JDK? Is Java free to use? Bug Fixes This release is based on the previous CPU and does not contain any additional security fixes.
The default ordered list is now: x, secpr1, secpr1, secpr1, x, ffdhe, ffdhe, ffdhe, ffdhe, ffdhe The default list can be overridden by using the system property jdk. The main change is Palestine ends DST earlier than predicted, on The main change is Fiji starts DST later than usual, on Bug Fixes This release also contains fixes for security vulnerabilities described in the Oracle Critical Patch Update.
For a more complete list of the bug fixes included in this release, see the JDK The named curves are listed below. With 47 weak named curves to be disabled, adding individual named curves to each disabledAlgorithms property would be overwhelming. To relieve this, a new security property, jdk. To use the new property in the disabledAlgorithms properties, precede the full property name with the keyword include.
Users can still add individual named curves to disabledAlgorithms properties separate from this new property. No other properties can be included in the disabledAlgorithms properties. To restore the named curves, remove the include jdk. Continuity Camera provides access to camera input, features, and effects on iPhone.
