233.0. "JDK V1.1.1 Beta Kit Released for Digital UNIX V4.0A or later" by TLE::DDAVIS (Dianne Davis - Java/C++ Product Manager * 381-6008 * ZKO02-3/N30) Wed May 28 1997 11:53

Note:  This beta update kit contains a new, faster Just-in-Time Compiler (JIT) which
achieves industry leading CaffeineMark and jBYTEmark benchmark results!


Digital Equipment Corporation is pleased to announce the availability of the

   Java Development Kit Beta V1.1.1 for Digital UNIX V4.0x Systems



The JDK V1.1.1 beta release replaces the JDK V1.1 beta kit that was
available on May 8, 1997. The JDK V1.1.1 beta release requires Digital UNIX
V4.0A or later.

Highlights of the DIGITAL JDK V1.1.1 release include:

   * Improved, Faster Just-in-Time (JIT) compiler which will provide
     increased run-time performance over the interpreter-based Virtual
     Machine. We have run CaffeineMark(tm) benchmarks with this JIT and the
     industry-leading results are shown below.
   * A POSIX threads implementation which will provide increased performance
     on multi-processor systems and increased robust interoperability with
     standards-conforming facilities such as DCE
   * First JDK 1.1.1 on 64-bit UNIX systems
   * Increased interpreter performance of the JDK 1.1.1 over the JDK 1.0.2
   * Compatibility with the Java Compatibility Kit (JCK). Currently this
     beta release passes more than 99% of the tests in the JCK.
   * Bugfixes for platform independent bugs. The JDK V1.1.1 beta release
     brings the Digital UNIX release in synch with Javasoft's latest
     releases and includes a number of fixes for platform independent bugs
     in the JDK V1.1 kit. A list of the bugs fixed in the JDK V1.1.1 can be
     found at: http://www.javasoft.com/products/jdk/1.1/fixedbugs/.
   * Enhancements to the JDK V1.1.1 over JDK 1.0.2 include:

        * Abstract Windowing Toolkit (AWT) Enhancements - Strong focus
          on quality and performance
        * Java Beans(TM) - Allows ISVs to create and ship Java
          components that can be composed together into applications by
          end users
        * Java Native Interface (JNI) - Standard programming interface
          for writing Java native methods and embedding Java virtual
          machine into native applications
        * Remote Method Invocation (RMI)- Create distributed
          Java-to-Java applications
        * JAR File Format - Java Archive file format
        * JDBC(TM)- Standard SQL database access interface
        * Networking Enhancements - Support for selected BSD-style
          socket options
        * IO Enhancements - Character streams, containing 16-bit
          Unicode characters
        * Math Package - BigInteger and BigDecimal classes
        * Object Serialization - Extends the core Java IO classes with
          support for objects
        * Reflection and Introspection - Enables Java code to find and
          access the fields, methods, and constructors of loaded
          classes
        * Inner Classes - Simpler syntax for creation of adapter
          classes
        * Internationalization - Allows development of localizable
          applets
        * Security and Signed applets - Allows developers to
          incorporate low-level and high-level security functionality
          into Java Applications

DIGITAL JIT: Industry-Leading Performance

An Alphastation 500/500, running DIGITAL UNIX and shipping today, has
attained the fastest CaffeineMark benchmark figure produced by any UNIX
vendor's system. Digital's JIT compiler attained a CaffeineMark version 2.01
score of 3,674, and a CaffeineMark version 2.5 score of 3,408. The
Alphastation 500/500 was running Digital UNIX V4.0B and was configured with
a 500Mhz 21164 Alpha chip, 128MB of memory, and 8mb of bcache using a
PowerStorm 4D60T graphic controller. As a convenience for comparing the
DIGITAL JIT performance with other vendors, we are providing the
CaffeineMark results for both V2.01 and V2.5. Indications from observing
other vendors' results are that certain tests report slower results with
V2.5 than with V2.01, and the DIGITAL JIT is consistent with that trend. In
the future, we will report results for V2.5, since that is the version that
will become most widely used. The numbers published below supersede the
results published on May 8, 1997.
