JDK, JRE Installation for Microsoft Windows (Itanium)

Installation procedure installs the JDK or JRE 6u7 but not the Java Plugin or Java Web Start (which are not available for 64-bit Windows) or public Java Runtime Environment (when JDK is installed).

To install, go to Java SE Downloads page, section 'JDK 6 Update 7 for Intel ItaniumPH*PH*PHuFFFDPH*PH*PH' if you need JDK, or 'JRE 6 Update 7 for Intel ItaniumPH*PH*PHuFFFDPH*PH*PH' if you need JRE.

On the Java SE Development Kit for Itanium 6u7 page (if JDK) or Java SE Runtime Environment for Itanium 6u7 page (if JRE), select 'Windows' platform.

Download jdk-6u7-windows-ia64.exe or jre-6u7-windows-ia64.exe file and then follow the 32-bit Windows JDK installation or 32-bit Windows JRE installation, 'Windows Offline Installation' instructions.

JDK, JRE Installation for Linux (Itanium)

Installation procedure installs the JRE or JDK 6u7 but not the Java Plugin or Java Web Start (which are not available for 64-bit Linux) or the public Java Runtime Environment (when JDK is installed).

To install, go to Java SE Downloads page, section 'JDK 6 Update 7 for Intel ItaniumPH*PH*PHuFFFDPH*PH*PH' if you need JDK, or 'JRE 6 Update 7 for Intel ItaniumPH*PH*PHuFFFDPH*PH*PH' if you need JRE.

The JDK, JRE for Linux 64-bit comes bundled in two install formats - Linux self-extracting files jdk-6u7-linux-ia64.bin, jre-6u7-linux-ia64.bin and Linux RPM in self-extracting files jdk-6u7-linux-ia64-rpm.bin, jre-6u7-linux-ia64-rpm.bin.

Download necessary file and then follow the 32-bit Linux JDK installation or 32-bit Linux JRE installation instructions.

Known installation issues

  • On Linux systems (specifically, on SLES 9) *-rpm.bin installation can report dmidecode unaligned access:

    However, the bundles install successfully. Message printing can be disabled by command 'prctl --unaligned=silent'.

  • On Linux systems, JDK (JRE) 6u7 can not be installed using jdk(jre)-6u7-linux-ia64-rpm.bin file if, on the same machine, JDK (JRE) 6u10 was previously installed using jdk(jre)-6u10-beta-linux-ia64-rpm.bin.

    Installation reports:

    Preparing... ########################################### [100%] package jdk-1.6.0_10-beta (which is newer than jdk-1.6.0_07-fcs) is already installed

    JDK (JRE) 6u7 is not installed.

    Workarounds are:

    • Un-install JDK (JRE) 6u10, then, install JDK (JRE) 6u7 using jdk(jre)-6u7-linux-ia64-rpm.bin, or
    • Install JDK (JRE) 6u7 using jdk(jre)-6u7-linux-ia64.bin file
    • If JDK (JRE) 6u10 was installed using jdk(jre)-6u10-beta-linux-ia64-rpm.bin, installation of JRE (JDK) 6u7 using jre(jdk)-6u7-linux-ia64-rpm.bin passes successfully.
  • On Windows systems after installation of JDK (or JRE) the registry key PH*PH*PHuFFFDPH*PH*PHHKEY_LOCAL_MACHINESOFTWAREJavaSoftJava Development Kit1.6PH*PH*PHuFFFDPH*PH*PH (for JDK), PH*PH*PHuFFFDPH*PH*PHHKEY_LOCAL_MACHINESOFTWAREJavaSoftJava Runtime Environment1.6PH*PH*PHuFFFDPH*PH*PH (for JRE) should contain value PH*PH*PHuFFFDPH*PH*PHJavaHomePH*PH*PHuFFFDPH*PH*PH with the full path name of the directory in which JDK (or JRE) of the highest version is installed.

    After installation of Itanium 6u7 JDK (or JRE) PH*PH*PHuFFFDPH*PH*PHJavaHomePH*PH*PHuFFFDPH*PH*PH contains the path to the last installed JDK (or JRE) instead of the path to the JDK (or JRE) of the highest installed version. After un-installation the value is removed.

    Workaround is to put the correct value to the Windows registry manually. See Deploying the JRE on Windows for more details about registry values.


  • Recommended options for running server applications with high performance are:
  • OSR (On Stack Replacement) is turned off by default. To turn it on, use PH*PH*PHuFFFDPH*PH*PHXX:+UseOnStackReplacement. This will likely improve performance of applications that contain long-running loops, and will not affect performance of other kinds of applications.

Known issues and limitations

  • JVM can intermittently crash with SIGILL on Linux RHEL4 Itanium when it is executed from NFS.

    This is a known bug in kernels of version less than 2.6.22. Processors older than Montecito (e.g. Madison, McKinley) are not affected. One can see details here:

    RHEL4 (Nahant Update 5), kernel 2.6.9-55.EL has this bug. In RHEL5.2(Tikanga), kernel 2.6.18-92.el5 the bug is fixed.

    Possible workarounds are:

    • Run java not from NFS.
    • Migrate to newer kernel in which this bug is fixed, for example, to RHEL5.2 or RHEL4.6.
    • Apply patch linux-2.6-mm-ia64-flush-i-cache-before-set_pte.patch (from kernel-2.6.18-92.el5.src.rpm) to your kernel.
  • JVM can intermittently crash when executed on Montecito or Montvale microprocessors, SLES 9 (any SP) operating system with Hyper-Threading enabled.

    Typically, the crash is caused by SIGILL (si_errno=0, si_code=1 (ILL_ILLOPC)) signal.

    Workarounds are:

    • Disable Hyper-Threading either completely (in BIOS) or partially for JVM process only using 'taskset' utility.
    • Use SLES 10.
  • Support for NUMA architectures is not fully implemented on Itanium yet, usage of option -XX:+UseNUMA may cause instability of the JVM.
  • JVM can intermittently crash on Windows 2003 Itanium platform when it is run from network drive. A workaround is to install the JRE on local disk. The problem disappears after installing 'Windows Server 2003 Service Pack 2 for Itanium-based Systems'
  • ALSA (Advanced Linux Sound Architecture, sound support is not included in this release.
  • Java 6 does not support Sun PKCS#11 and SunMSCAPI providers for Windows 64-bit (see native security features availability in various operating systems in Leveraging Security in the Native Platform Using Java SE 6 Technology article). These providers are not a part of Java 6 for Windows Itanium. If necessary, one can use implementations of these providers offered by third parties.

An error “you need to install the legacy Java SE 6 runtime”, is encountered when you open any Adobe application.

Java 6 For Mac Download Free Version

With Mac OS 10.7 (Lion) and later, the Java runtime is no longer installed automatically as part of the OS installation. Follow any of the methods below to install Java runtime.

You can download and install the latest Java runtime from the Java website - Download Free Java Software.


On Mac OS 10.10 (Yosemite), when you launch any Adobe product, you might receive a warning 'The Application has been moved and its path has been changed...'.

Click Repair Now or Update button to update the location and resolve the issue. When prompted for password, enter your system password to complete.

If Java runtime is not installed, you are prompted to install when you first launch any Adobe product. Follow the onscreen instructions in the Java required notification dialog box to install.

Use the following method to initiate the Java runtime installation or confirm if it is installed.

  1. Go to Applications > Utilities > Java Preferences.
  2. If Java is not installed, you receive the following message: “To open “Java Preferences,' you need a Java runtime. Would you like to install one now?”

  3. Click Install and accept the license agreement. The Java runtime is downloaded and installed.

Many Adobe applications depend on the Oracle Java Runtime Environment (JRE) for some features to work. Apple recently changed the way it includes Java in Mac OS, and with Lion, Java is no longer preinstalled. It is now an optional install that you must select.

Since current Adobe installers and applications were built before these changes by Apple, Adobe software anticipates that Java is installed. Adobe and Apple have worked together to ensure that you can install Java at OS install time. Or it can be installed later before you install Adobe applications. At runtime, when you launch an Adobe application, you are prompted to install Java if it is not already installed. If you do not install Java before running an Adobe application, there can be missing or improperly behaving features. If you encounter any issues, install Java to correct the problems. Adobe recommends that corporate IT organizations pre install Java (or make sure that Java can be installed through their firewalls/security) to avoid conflicts with Adobe applications.

If the Java runtime is not installed, some issues that are known to occur include -
