Install Java runtime prompts when you attempt to use the applications.
If the Java runtime is not installed, some issues that are known to occur include.
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. Easy install Macs that come installed with OS X 10.8. If you encounter any issues, install Java to correct the problems. Java for macOS 2017-001 installs the legacy Java 6 runtime for macOS 10.13 High Sierra, macOS 10.12 Sierra, macOS 10.11 El Capitan, macOS 10.10 Yosemite, macOS 10.9 Mavericks, macOS 10.8 Mountain Lion, and macOS 10.7 Lion. If you do not install Java before running an Adobe application, there can be missing or improperly behaving features. This package is exclusively intended for support of legacy software and installs the same. At runtime, when you launch an Adobe application, you are prompted to install Java if it is not already installed. Java for macOS 2017-001 installs the legacy Java 6 runtime for macOS 10.13 High Sierra, macOS 10.12 Sierra, macOS 10.11 El Capitan, macOS 10.10 Yosemite, macOS 10.9 Mavericks, macOS 10.8 Mountain Lion, and macOS 10.7 Lion. Or it can be installed later before you install Adobe applications. Adobe and Apple have worked together to ensure that you can install Java at OS install time. So my question is: How safe is it for me to install Java on Mac OS X 10.8.3 (The hidden question inside this question is what version / source of Java I should select if I can depend on Apple to keep Java secure.) I understand 'safeness' is a fairly difficult thing to define, but just some general advice would be greatly appreciated. Since current Adobe installers and applications were built before these changes by Apple, Adobe software anticipates that Java is installed. It is now an optional install that you must select. Apple recently changed the way it includes Java in Mac OS, and with Lion, Java is no longer preinstalled. Many Adobe applications depend on the Oracle Java Runtime Environment (JRE) for some features to work.
