I’ve an IntelliJ 13 app but it can’t be executed with the new Java versions, but it could be configured to use a specific Java version.
1. Open the app with the context menu and select Shows Package Content
2. Edit the file Contents/Info.plsit and edit the next section to select the base version, in this example I’ve using the Java 1.8.
<key>JVMVersion</key>
<string>1.8*</string>
3. Save the file and execute the app.
