Oracle Java 10 JDK and JRE installation scripts for macOS

April 19, 2018 Leave a comment

Oracle has started to release Java 10 for macOS, so I’m posting a couple of scripts to download and install the following:

Oracle has been releasing two separate versions of Java 8 simultaneously and may do the same for Java 10, so these Java 10-focused scripts are designed to allow the user to set which version they want to install: the CPU release or the PSU release.

The difference between CPU and PSU releases is as follows:

  • Critical Patch Update (CPU): contains both fixes to security vulnerabilities and critical bug fixes.
  • Patch Set Update (PSU): contains all the fixes in the corresponding CPU, plus additional fixes to non-critical problems.

For more details on the differences between CPU and PSU updates, please see the link below:

Automating Oracle Java 8 JDK updates

July 29, 2016 Leave a comment

To go along with a previous post about automating Oracle Java 8 updates, I’ve now posted a script to download and install the latest Java 8 Java Development Kit (JDK) from Oracle. Oracle has been releasing two separate versions of Java 8 simultaneously, so this script is designed to allow the user to set which version they want to install: the CPU release or the PSU release.
The difference between CPU and PSU releases is as follows:

  • Critical Patch Update (CPU): contains both fixes to security vulnerabilities and critical bug fixes.
  • Patch Set Update (PSU): contains all the fixes in the corresponding CPU, plus additional fixes to non-critical problems.

For more details on the differences between CPU and PSU updates, please see the link below:

Java 8 Update 65 Redux – The Good, the Bad and the Failings

November 13, 2015 Leave a comment

With the release of Java 8 Update 65, Oracle has returned to using an application to install Java. This switch away from using installer packages is a problem for Mac admins who need to deploy Oracle’s Java 8 in their own environment. However, after doing some research, it looks like it is still possible to deploy Oracle’s Java 8 Update 65 using a standard installer package. For more details, see below the jump.

Oracle’s Java 8 Update 66

Following closely on the heels of Oracle’s release of Java 8 Update 65, Oracle has released Java 8 Update 66. This update is also using Oracle’s install application.

What’s the difference between Update 65 and Update 66? Update 65 is a Critical Patch Update (CPU), which contains both fixes to security vulnerabilities and critical bug fixes. Update 66 is a Patch Set Update (PSU), which means it contains all the fixes in the corresponding CPU, plus additional fixes to non-critical problems. For more details on the differences between CPU and PSU updates, please see the link below:

So the short version is that Update 65 has “critical bug fixes” and Update 66 has “Update 65’s bug fixes, plus more bug fixes.”

You can get Oracle’s Java 8 Update 66 from the link below:

Oracle’s Java 8 Update 65 – The return of the Java install application

October 20, 2015 5 comments

For the past couple of releases, Oracle has used a standard installer package to install Java 8. With the release of Java 8 Update 65 though, Oracle returned to using an application to install Java.

Modifying Oracle’s Java SDK to run Java applications on OS X

August 8, 2015 3 comments

As part of releasing the developer betas for OS X 10.11, Apple announced that El Capitan would be the end of the line for the Java 6 runtime and tools provided by Apple, with the clear statement that developers should be moving on to Oracle’s Java tools.

To completely replace Apple’s Java 6 tools, Oracle’s Java JDK (Java SE Development Kit) will need to be installed. This is because the Oracle Java JRE (Java Runtime Environment) on OS X is a browser plug-in for running Java via a web browser and does not include capabilities for running Java desktop apps or command line tools.

By default though, the Oracle JDK does not set several options to advertise the capabilities provided by the JDK to Java apps, which may cause applications that need those capabilities to fail to launch. The capabilities are actually present in the JDK, but those options need to be set before applications will recognize them as available.

To fix this, we need to add the following options to Oracle’s Java JDK:

  • BundledApp
  • JNI

 In turn, enabling these options means they need to be added to the list of JVMCapabilities stored in the following plist file:

/Library/Java/JavaVirtualMachines/jdk_version_info_goes_here.jdk/Contents/Info.plist
