JDK 7 Features


This is the list of features being developed by Oracle, and others, for JDK 7.

When the Java SE 7 Platform JSR is submitted then these features will be proposed therein, except for those listed as implementation-specific.

Comments to: jdk7-dev at openjdk.java.net


Features are listed in order, more or less, from lowest to highest in the overall JDK  software stack.

vm JSR 292: Support for dynamically-typed languages (InvokeDynamic)
lang JSR TBD: Small language enhancements (Project Coin) [UPDATED]
core Upgrade class-loader architecture
Method to close a URLClassLoader
Concurrency and collections updates (jsr166y)
i18n Unicode 6.0 [UPDATED]
Locale enhancement [NEW]
Separate user locale and user-interface locale [NEW]
ionet JSR 203: More new I/O APIs for the Java platform (NIO.2)
NIO.2 filesystem provider for zip/jar archives [NEW]
SCTP (Stream Control Transmission Protocol)
SDP (Sockets Direct Protocol)
Use the Windows Vista IPv6 stack [NEW]
TLS 1.2 [NEW]
sec Elliptic-curve cryptography (ECC)
jdbc JDBC 4.1 [NEW]
client XRender pipeline for Java 2D
Create new platform APIs for 6u10 graphics features
Nimbus look-and-feel for Swing
Swing JLayer component
web Update the XML stack

This list contains some [NEW] features which were not part of the previous JDK 7 plan but have been added because we expect them to have high value for developers and users and because they are essentially finished.

Some features have also been [UPDATED], in which case details are given below.

Two VM features previously listed here, the Garbage-First garbage collector and compressed pointers, have been removed because they have already been implemented in JDK 6.

Features that were once planned for JDK 7 but later deferred to JDK 8 or a later release are listed at the bottom of this page.

JSR 292: Support for dynamically-typed languages (InvokeDynamic)
VM and language extensions to support the implementation of dynamically-typed languages at performance levels near to that of the Java language itself
Lead: John Rose
Milestone target: M3
JSR TBD: Small language enhancements (Project Coin) [UPDATED]
A set of small language changes intended to simplify common, day-to-day programming tasks: Strings in switch statements, automatic resource management, improved type inference for generic instance creation (“diamond”), simplified varargs method invocation, better integral literals, and improved exception handling (multi-catch) [UPDATE: Language support for collections has been deferred]
Lead: Joe Darcy
Upgrade class-loader architecture
Modifications to the ClassLoader API and implementation to avoid deadlocks in non-hierarchical class-loader topologies
Lead: Karen Kinnear
Links: summary
Milestone target: M3
Method to close a URLClassLoader
A method that frees the underlying resources, such as open files, held by a URLClassLoader
Links: summary; api
Milestone target: M2
Concurrency and collections updates (jsr166y)
A lightweight fork/join framework, flexible and reusable synchronization barriers, transfer queues, a concurrent-reference HashMap, and thread-local pseudo-random number generators
Lead: Doug Lea
Milestone target: M5
Unicode 6.0 [UPDATED]
Upgrade the supported version of Unicode to 6.0 [UPDATE: Changed from the original goal of Unicode 5.1)
Lead: Yuka Kamiya
Locale enhancement [NEW]
Upgrade the java.util.Locale class to support IETF BCP 47 and UTR 35 (CLDR/LDML)
Links: overview
Separate user locale and user-interface locale [NEW]
Upgrade the handling of locales to separate formatting locales from user-interface language locales, as is done on Vista and later versions of Windows
I/O and Networking
JSR 203: More new I/O APIs for the Java platform (NIO.2)
New APIs for filesystem access, scalable asynchronous I/O operations, socket-channel binding and configuration, and multicast datagrams
Milestone target: M2
NIO.2 filesystem provider for zip/jar archives [NEW]
A fully-functional and supported NIO.2 filesystem provider for zip and jar files
SCTP (Stream Control Transmission Protocol)
An implementation-specific API for the Stream Control Transmission Protocol on Solaris
Milestone target: M3
SDP (Sockets Direct Protocol)
Implementation-specific support for reliable, high-performance network streams over Infiniband connections on Solaris and Linux
Milestone target: M3
Use the Windows Vista IPv6 stack [NEW]
Upgrade the networking code to use the Windows Vista IPv6 stack, when available, in preference to the legacy Windows stack
TLS 1.2 [NEW]
Add support for TLS 1.2, which was standardized in 2008 as RFC 5246
Security & Cryptography
Elliptic-curve cryptography (ECC)
A portable implementation of the standard Elliptic Curve Cryptographic (ECC) algorithms, so that all Java applications can use ECC out-of-the-box

JDBC 4.1 [NEW]
Upgrade to JDBC 4.1 and Rowset 1.1
Lead: Lance Andersen
