To use the “java” command-line tool you need to install a JDK.

    Ever since I up graded from 10.7.5 to Sierra I get this pop up from time to time. Some times at start up other times just random. I cleaned out my start up items. I have the latest Java installed. What in Sierra needs the full JDK installed ? Are there any security issues by installing it or how do I make it go away ?

    I have this sneaky feeling that it's looking for the old MRJ from Apple. Or maybe it's not the current Java from Oracle. However, I do have that sneaky feeling about Ye Olde Java from Apple.
