My thoughts on Slackware, life and everything

April 15 Java security update: OpenJDK 7u79

icedtea A new release of IcedTea  is available. Version 2.5.5 of the “Java build framework” will create OpenJDK 7 “Update 79 Build 14” (resulting in a Slackware package openjdk-7u79_b14).

The release announcement can be found on the blog of release maintainer Andrew Hughes. The update synchronizes OpenJDK with Oracle’s April ’15 security updates. This will be Oracle’s final update to the Java 7 codebase. I expect that the next release of Icedtea will give us OpenJDK 8.

A list of  CVE’s is associated with the new release. Here are all security fixes mentioned in the post:

The new Java is properly detected by the java tester page at but Oracle’s Java version tester at only mentions that this version of Java is no longer supported (it wants us all to move to Java 8 on Windows I guess):


Note about usage:

Remember that I release packages for the JRE (runtime) and the JDK (development kit) simultaneously, but you only need to install one of the two. The JRE is sufficient if you only want to run Java programs (including Java web plugins). Only in case where you’d want to develop Java programs and need a Java compiler, you are in need of the JDK package. Get them here.

The Java package (openjre as well as openjdk) has one dependency: rhino provides JavaScript support for OpenJDK.

Optionally: If you want to use Java in a web browser (which supports NPAPI plugins – this excludes Chrome & Chromium but you’ll be OK with all Mozilla [-compatible] browsers) then you’ll have to install my icedtea-web package too. While Oracle’s JDK contains a browser plugin, that one is closed-source and therefore Icedtea offers an open source variant which does a decent job.

If you want to compile this OpenJDK package yourself, you need to install apache-ant additionally. Note that the previous requirements of xalan & xerces packages have been dropped; ant will provide all required build functionality on its own now.

Have fun! Eric

    Just upgraded to openjre-7u79_b14-x86_64-1alien.txz on Slackware-current after the April 21 updates.

    You have the recommended Java installed (1.7.0_79). ”
    And, as always, my grateful thanks for all your hard work on Slackware.

    Thank you very much for this! I was using LibreOffice Base on Slackware 14.1 64 bit with the default Java package and was experiencing slowness and 100% CPU usage with only modest data sets. Changing to this Java package made a very big speed improvement and it runs fine for me now – thanks very, very much!
