Fixing RubyMine 7.1.4 Crash with Java 9 on Mac OS 10.12

Hey there, let's break down why this crash is happening and how to fix it quickly.

The Root Cause

Your issue boils down to compatibility: RubyMine 7.1.4 is an older IDE version built to work with Java 8 and earlier. Java 9 removed several classes from the sun.misc package—including the sun/misc/resource class your error mentions. That’s why setting JAVA_HOME alone didn’t resolve the problem; the IDE can’t find the required class in Java 9.

Step-by-Step Solutions

1. Downgrade to Java 8 (Recommended)

The most reliable fix is pairing RubyMine 7.1.4 with Java 8. Here’s how to switch on Mac:

First, check if you have Java 8 installed by running this in Terminal:
```
/usr/libexec/java_home -v 1.8
```
If it returns a file path, you’re set. If not, download Java 8 from Oracle’s official archive.
Temporary switch: Run these commands in Terminal to set Java 8 as your current JDK and launch RubyMine:
```
export JAVA_HOME=$(/usr/libexec/java_home -v 1.8)
open /Applications/RubyMine.app
```
Permanent switch: Edit your shell profile file (either ~/.bash_profile or ~/.zshrc, depending on your default shell) and add:
```
export JAVA_HOME=$(/usr/libexec/java_home -v 1.8)
```
Save the file, then run source ~/.bash_profile (or source ~/.zshrc) to apply the changes immediately.

2. Force RubyMine to Use Java 8 via Launch Config

If you need to keep Java 9 for other apps, you can tell RubyMine specifically to use Java 8:

Navigate to RubyMine’s installation directory: /Applications/RubyMine.app/Contents/bin
Open the rubymine.vmoptions file (or idea.vmoptions—they’re interchangeable in older versions) with a text editor.
Add this line at the bottom, replacing the path with your actual Java 8 home path (from the java_home command earlier):
```
-jdkhome /Library/Java/JavaVirtualMachines/jdk1.8.0_xxx.jdk/Contents/Home
```
Save the file and restart RubyMine.
