Apple's Java product manager Gary Little says that Apple "should be posting an MRJ 2.0 SDK (final) by the end of January." This basically will be the MacOS version of the Java Development Kit (JDK) that Sun had originally promised for release last June. As with MRJ, the SDK is being released to developers as it evolves.
WHAT IS THE LATEST JAVA RUNTIME FOR MAC SOFTWARE
The corresponding Software Development Kit (SDK) is not quite ready yet. Other supported features mean more to developers than to the average user: There is support for inner classes, the new event model, changes to the abstract window toolkit (AWT), object serialization, and reflection. With MRJ 2.0, the MacOS VM supports JavaBeans, the JAR file format, Remote Method Invocation (RMI), Java Database Connectivity (JDBC), and Java Native Interface (JNI). The company already has people working on 1.2. Apple still plans to close the gap between the Sun JDK release and the corresponding Apple MRJ release. The final version was released on December 20, shortly after Sun released beta versions of the Java Development Kit (JDK) 1.2 for Windows 95/NT and Solaris. Instead, Apple provided a series of seven early access releases to developers as the product moved from alpha to beta.
WHAT IS THE LATEST JAVA RUNTIME FOR MAC INSTALL
On the download page, Apple recommends "that everyone download and install this version immediately to gain the advantages provided by all the latest Java features it incorporates." Despite the importance of this release, Apple does not plan to include this news in a formal press release until January 6, and currently its "hot news" page suggests that you upgrade to the now-outdated MRJ 1.5.1.Īt MacWorld Expo in Boston last August, Apple promised to make MRJ 2.0 available in public beta by the end of September. See the Resources section for a link to the announcement of the release the release page contains links to download sites. The release also includes versions of the just-in-time compiler (JIT) for both the PowerPC and for 68040 Macs. Apple's numbering system for its releases differs from Sun's, but this release of the MacOS implementation of the Java virtual machine (JVM) and related libraries corresponds to version 1.1.3 of Sun's Java specification. You can now download the long-awaited MacOS Runtime for Java (MRJ) version 2.0.
