The move caught Mac users by surprise, the Associated Press reports. Apple maintains blacklists that are communicated to Macs that connect to the Internet. The list prevents recent Macintosh operating systems from running the latest version of Java as well as some older versions. Once the lists downloaded, the machines would no longer use and Java-based code and users could no longer run programs or web applications based on Java.
In January, the U.S. Department of Homeland Security reported a critical security hole in Java and recommended that all computers have Java disabled. Oracle has issued updates that the company says fix the issue, but DHS continues to believe that there are other, as yet unknown, security issues in the program’s code.
