I screwed it up! I upgraded to Java 8 yesterday and that trashed some projects I was working on so I attempted to downgrade back to Java 7 and the wheels came off.

I've removed the previous Java directories in both JavaVM.framework and JavaVirtualMachines.

I re-ran the jdk-7u71-macosx-x64 and it complains during validation. The extremely informative: The Installation encountered an error ... blah blah.. go contact someone who cares. No details as to why it fails.

so freaking helpful

I can verify its presence though:

 ls -l /Library/Java/JavaVirtualMachines/jdk1.7.0_71.jdk/*

 drwxrwxr-x  15 root  wheel   510 Mar 28 09:03 Home

 drwxrwxr-x   3 root  wheel   102 Mar 28 09:03 MacOS

including:

java -version

Also have it linked back to /usr/bin/java and /Library

When I try to run eclipse or mvn it complains Platform Not Recognized. Most especially around the FileSystem.

How do I get the underlying libraries back on here?

(My backups are up to date... Is there something I can restore that would help my situation or will I only make things worse?)

I think you now need to re-install the "old" Apple Java, so it can link it self up again.

Download Java for OS X 2014-001, and install it - this will re-install /System/Library/Frameworks/JavaVM.framework, and just to be sure, install Java 7_75 or 7_76 (the newest update for Oracle Java) again.

Try adding the JVM parameter: -Dos.name=Linux

  • Thank you for this, it worked in my case!!! – Kostanos Jun 27 at 0:51
