Where Does Java 8 Go on Mac? Resolving Oracle\'s Installation Enigma.

How to Install Java 8 on Mac: Navigating Oracle's Quirks

This article addresses the installation challenges faced by Mac users attempting to install Java 8 for developing with JavaFX. Despite running Oracle's installer, the files appear to be placed in an unexpected location (/Library/Java/...), causing difficulties in locating and setting the current Java version.

Oracle's Installation Enigma

The disparity between Oracle's installer placement of Java 8 (/Library/... vs. /System/Library/...) presents a perplexing issue. The System Preferences "Java" control panel ironically displays Java 1.8, contradicting the absence of the corresponding version in /usr/libexec/java_home -V.

Homebrew to the Rescue

Fortunately, Homebrew provides a solution to these installation woes. Using Homebrew, users can conveniently install the latest OpenJDK (Java 14) directly into an appropriate location with the command:

brew install --cask adoptopenjdk8

For cases requiring an older version (e.g., Java 8), the AdoptOpenJDK project allows for an additional step to install Java 8:

brew tap adoptopenjdk/openjdk
brew install --cask adoptopenjdk8

Users with existing Homebrew installations may encounter an error related to multiple taps. This can be resolved by specifying the location explicitly:

brew install --cask adoptopenjdk/openjdk/adoptopenjdk8
