I’m not an expert on Java, but I can only assume that things have changed and backward compatibility wasn’t high on ORACLE’s priority list. This happens because CS5 and CS6 applications were relying on Java 6, and the current version at the time of writing is Java 8. I guess eclipse requires this.When you’re trying to open any of the Adobe CS5 or CS6 applications in Yosemite, you’ve likely encountered a friendly message such as this: I resolved the issue by simply installing 1.8.x JDK instead of the JRE, despite having no intension to develop for Java. I followed every suggestion I could find over numerous forums with no success. I'm unclear on the security implications of this though, would have preferred another solution, if anyone finds a better solution than installing 6 please let me know. I ended up relenting and downloading Java 6 from here:Īpparently this seems to coexist ok with the latest Java version which I also installed (version 8 update 25) and version 8 shows up as the version I'm running when I verify from In any case, that wasn't sufficient - I also had to change the JDK ist and security as described above for a complete solution. However, I'm not sure that's strictly required. When I was solving this on MTGBrowser (below) I also followed advice to change the ist of the app by adding the following section to the 'Eclipse' key: -vm/Library/Java/JavaVirtualMachines/jdk1.8.0_25.jdk/Contents/Home/bin/java This opens Eclipse without requiring the separate download of the legacy Java SE 6 files. Go to System Preferences: Security Settings (General) and you should see the recent app next to a button "Open Anyway" - click this button to open the app.


You should get an error "(app) can't be opened because it is from an unidentified developer." Try to open the app from the command-line (not sure if this is strictly necessary, but what I did)

Other configurations might work this is my environment.Įdit the ist for the JDK after installing: $ sudo nano `/usr/libexec/java_home -V`/./istĬhange the following section: JVMCapabilities Java HotSpot(TM) 64-Bit Server VM (build 25.25-b02, mixed mode) Java(TM) SE Runtime Environment (build 1.8.0_25-b17) Here are the steps in case it helps other devs get Eclipse working. I just encountered this in another Eclipse-based app on Yosemite and figured out (with help from the references below) how to get the app running without installing the legacy Java SE 6 JRE.
