Issue Description

Support for X25519 and X448 in TLS

The named elliptic curve groups x25519 and x448 are now available for JSSE key agreement in TLS versions 1.0 to 1.3, with x25519 being the most preferred of the default enabled named groups. The default ordered list is now:

` x25519, secp256r1, secp384r1, secp521r1, x448, sect283k1, sect283r1, sect409k1, sect409r1, sect571k1, sect571r1, secp256k1, ffdhe2048, ffdhe3072, ffdhe4096, ffdhe6144, ffdhe8192 `

The default list can be overridden using the system property jdk.tls.namedGroups.


Issue Description

Added a Default Native GSS-API Library on Windows

A native GSS-API library named sspi_bridge.dll has been added to the JDK on the Windows platform. The library is client-side only and uses the default credentials. It will be loaded when the system property is set to "true". A user can still load a third-party native GSS-API library by setting the system property to the appropriate path.

Native GSS automatically uses cached credentials from operating systems, thus the system property should be set to false. does not call native JGSS. Avoid using from JAAS config.


Issue Description

-groupname Option Added to keytool Key Pair Generation

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 secp384r1 will generate an EC key pair by using the secp384r1 curve. Because there might be multiple curves with the same size, using the -groupname option is preferred over the -keysize option.


jarsigner Preserves POSIX File Permission and symlink Attributes

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.

Note that the jar tool does not read/write these attributes. This change is more visible to tools like unzip where these attributes are preserved.


Issue Description

US/Pacific-New Zone Name Removed as Part of tzdata2020b

Following the JDK's update to tzdata2020b, the long-obsolete files named pacificnew and systemv have been removed. As a result, the "US/Pacific-New" Zone name declared in the pacificnew data file is no longer available for use.

Information regarding this update can be viewed at
