Eclipse, OS X, and SoyLatte

Current revisions of Eclipse prevent the use of SoyLatte, the OpenJDK port of Java 1.6 for OS X 10.4/10.5. There is an open bug about this, and even better a patch for StandardVMType attached to the bug. I've applied the patch and it does indeed work. There is actually only a single jar used by Eclipse that needs to be built, and most of this can be done within Eclipse itself. The steps for doing this are outlined below.


  1. Download the Eclipse source. Unzip it.
  2. From within Eclipse do File | Import... | Existing Projects into Workspace and hit Next. Set your root directory to ${eclipse_src}/plugins/org.eclipse.jdt.launching. Copy the project into the workspace, just to save potential trouble.
  3. Check out the patch. Copy it to your clipboard.
  4. To apply the patch go to StandardVMType.java in the Package Explorer, right click, Team | Apply Patch...
  5. Now to export the plugin, i.e. build the jar needed by Eclipse. Again from within Eclipse: File | Export... | Plug-In Development | Deployable plugs-ins and fragments. Check off the plugin and perhaps change the output directory. Hit finish. You should have the jar with the applied patch in your output directory now.
  6. Exit Eclipse.
  7. From your Eclipse home directory (not the source installation, your binary install directory), go to plugins/ and find a file that is named something like org.eclipse.jdt.launching_3.3.1.v20070808_r331.jar. Move this file to a backup directory of your choosing. 
  8. Copy the file generated in step (5) to here.
  9. Restart Eclipse.
  10. Go to Eclipse preferences | Java | Installed JREs and try and add SoyLatte as a JRE. If everything worked you should be able to do so without error.
Good luck. Let me know if this works for anyone.

Update: The above works with Eclipse Europa, but not Ganymede. I am currently investigating how to get SoyLatte working with Ganymede.

hi james,

could you please post the patched jar file (either here or at the issue)? i could not compile the class for some reason (it looked like the patch is not uptodate)

I would really appreciate any help!

thank you for your help in advance.

James,

Look forward to seeing you solve this problem for Ganymede. It's annoying for us old-32-bit MacBookPro owners to not be able to use Java 1.6 with Eclipse.

Now, if you could only solve the problem of running RCP apps on Soylatte, tha'd be great :)

thanks a lot for your writeup

Thanks for the help. It saved me, even though I have the standard JVM installed and Eclipse will come up correctly and use that JRE, a self-hosted instance (vital for debugging plugins...) would not let me set the JRE to the Apple one. Your patch was a lifesaver... Well at least saves me from doing more work in a virtualized Windows... Man Eclipse on Java 64bit is soo much nicer.
