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
