Java for OS X 2015-001 installs the legacy Java 6 runtime for OS X 10.11 El Capitan, OS X 10.10 Yosemite, OS X 10.9 Mavericks, OS X 10.8 Mountain Lion, and OS X 10.7 Lion. This package is exclusively intended for support of legacy software and installs the same deprecated version of Java 6 included in the 2014-001 and 2013-005 releases. After I updated to Mac OS X 10.10 (Yosemite) or 10.11 (El Capitan), why am I continually prompted to install Java again? How do I control when an untrusted applet or application runs in my web browser? How do I install Java on Mac OS X 10.10? How do I install Java without third party sponsor offers? Printing Issues.

Hi guys, I noticed I was getting a lot of traffic, so I updated my post for the latest version of Java, and added a note for El Capitan's Rootless mode down the bottom. I think it would be better to recommend disabling Rootless mode and to restart manually.

My previous post about installing Java on OS X received quite a bit of traffic, and I felt that some of the information was outdated, and it became a little unclear after all the edits, so I’ve endeavoured to create a much easier to understand set of instructions.

The instructions for installing the JDK (Java Development Kit) are a subset of the instructions for installing just the JRE, because Oracle provides an installer for the JDK.

Java El Capitan Mac

  1. Go to the Oracle Java downloads page and download the JDK installer. You should end up with a file named something similar to jdk-8u60-macosx-x64.dmg, but perhaps a newer version.
  2. Open the .dmg Disk Image and run the installer.
  3. Open Terminal
  4. Edit the JDK’s newly installed Info.plist file to enable the included JRE to be used from the the command line, and from bundled applications:

    The third line fixes a permissions issue create by using defaults write. The fourth line is not required, but makes the file more user-friendly if you open it again in a text editor.

  5. Create a link to add backwards compatibility for some applications made for older Java versions:
  6. Optional: If you’re actually using the JDK for software development, you may want to set the JAVA_HOME environment variable. The recommended way is to use /usr/libexec/java_home program, so I recommend setting JAVA_HOME in your .bash_profile like Jared suggests:

    This will get the latest installed Java’s home directory by default, but check out man java_home for ways to easily get other Java home directories.

You should be done now, so try and open the application. If it does not work, some applications require legacy Java 6 to be installed. You can have it installed without actually using it, however, it’s possible to trick the applications into thinking legacy Java 6 is installed, without actually doing so.

If you’re running El Capitan, this is actually a little difficult now, because Apple added SIP (System Integrity Protection) to OS X. I have written a post explaining how to disable and enable SIP.

If you’ve disabled SIP, or are not running El Capitan yet, you can trick some applications into thinking legacy Java 6 is installed by creating two folders with the following commands in Terminal:

Don’t forget to enable SIP again after creating these directories.

Java™ SE Development Kit 7, Update 91 (JDK 7u91)

The full version string for this update release is 1.7.0_91-b15 (where 'b' means 'build'). The version number is 7u91.

This update release contains several enhancements and changes including the following:

IANA Data 2015f

JDK 7u91 contains IANA time zone data version 2015f. For more information, refer to Timezone Data Versions in the JRE Software.

Security Baselines

The security baselines for the Java Runtime Environment (JRE) at the time of the release of JDK 7u91 are specified in the following table:

JRE Family VersionJRE Security Baseline (Full Version String)
71.7.0_91
61.6.0_105

For more information about security baselines, see Deploying Java Applets With Family JRE Versions in Java Plug-in for Internet Explorer.

JRE Expiration Date

Capitan

Java For Mac Os X El Capitan

The JRE expires whenever a new release with security vulnerability fixes becomes available. Critical patch updates, which contain security vulnerability fixes, are announced one year in advance on Critical Patch Updates, Security Alerts and Third Party Bulletin. This JRE (version 7u91) will expire with the release of the next critical patch update scheduled for January 19, 2016.

For systems unable to reach the Oracle Servers, a secondary mechanism expires this JRE (version 7u91) on February 20, 2015. After either condition is met (new release becoming available or expiration date reached), the JRE will provide additional warnings and reminders to users to update to the newer version. For more information, see JRE Expiration Date.

Notes

When running on OSX 10.11 'El Capitan', when SIP is enabled, certain environment variables intended for debugging applications, such as DYLD_LIBRARY_PATH, may be stripped from the environment when running Java from the command line or when double-clicking a JAR file. Applications should not rely on these variables in a production environment, they are only intended for debugging during development.

New Features and Changes

The following are some of the notable new features and changes in this release:

dns_lookup_realm should be false by default
The dns_lookup_realm setting in Kerberos' krb5.conf file is by default false.

See JDK-8080637.

Support ISO 4217 'Current funds codes' table (A.2)
This enhancement adds support for ISO 4217 table A.2 fund codes. Previously the JDK only supported those currencies listed in table A.1.

See JDK-8074350.

DHKeyPairs with Bit Lengths Greater Than 1024
DHKeyPair generation now supports use of key sizes up to 2048 bits. Key size must be multiples of 64 if less than 1024 bits, or 2048 bits.

See JDK-8062834.

Bug Fixes

Download

This release contains fixes for security vulnerabilities. For more information, see Oracle Java SE Critical Patch Update Advisory. For a list of bug fixes included in this release, see JDK 7u91 Bug Fixes page.
The following are some of the notable bug fixes included in this release:

Use Safe Prime Diffie-Hellman Groups
In the JDK SSL/TLS implementation (SunJSSE provider), safe prime Diffie-Hellman groups are used by default. Users can customize Diffie-Hellman groups with the security property, 'jdk.tls.server.defaultDHEParameters'.

Kerberos changes for applications running with security manager
This JDK release introduces some changes to how Kerberos requests are handled when a security manager is present.

Update Java Mac El Capitan

Note that if a security manager is installed while a KerberosPricipal is being created, a {@link ServicePermission} must be granted and the service principal of the permission must minimally be inside the {@code KerberosPrincipal}'s realm.

For example, if the result of {@code new KerberosPrincipal('user')} is {@code user@EXAMPLE.COM}, then a {@code ServicePermission} with service principal {@code host/www.example.com@EXAMPLE.COM} (and any action) must be granted.

Also note that if a single GSS-API principal entity that contains a Kerberos name element without providing its realm is being created via the org.ietf.jgss.GSSName interface and a security manager is installed, then this release introduces a new requirement. A {@link javax.security.auth.kerberos.ServicePermission ServicePermission} must be granted and the service principal of the permission must minimally be inside the Kerberos name element's realm.

Java El Capitan Update

For example, if the result of {@link GSSManager#createName(String, Oid) createName('user', NT_USER_NAME)} contains a Kerberos name element {@code user@EXAMPLE.COM}, then a {@code ServicePermission} with service principal {@code host/www.example.com@EXAMPLE.COM} (and any action) must be granted. Otherwise, the creation will throw a {@link GSSException} containing the {@code GSSException.FAILURE} error code.

JDK-8048030 (not public)

Hotspot should use PICL interface to get cacheline size on SPARC

The libpicl library is now required on Solaris/SPARC to determine the size of the cache lines. In case the library is not present or the PICL service is not available the JVM will display a warning and compiler optimizations that utilize the BIS (Block Initializing Store) instruction will be turned off.

See JDK-8056124.

Preloading libjsig.dylib causes deadlock when signal() is called
Applications need to preload the libjsig library to enable signal chaining. Previously, on OS X, after libjsig.dylib was preloaded, any call from native code to signal() caused a deadlock. This has been corrected.
