/usr/bin Permission change OSX 10.9 Mavericks I am trying to set up Java on Xcode and it needs to access /usr/bin/java at some point. But I cannot get hold of this folder and I get this message: The folder “java” can’t be opened because you don’t have permission to see its contents. 

Even when I try to reach the permission through Get Info the system does not open the folder because of the same restriction.

I think it is possible to change the permission through Terminal but I am afraid to blow up something on my Mac. How can I change the permission safely?
/usr/bin/java is no valid folder in any installation or version of Java (I know of).

Instead the file /usr/bin/java is a symlink to /System/Library/Frameworks/JavaVM.framework/Versions/A/Commands/java installed by the default Apple Java installer (v1.6.x).

The Oracle Java installer (either JDK/SDK or JRE) is installed to /Library/Java.
