A short while ago I read a DZone article that reminded me of some things developers should try to do on a regular basis.  In addition to staying current (or trying to do so) with all that's going on in our fun and fast-paced field, we should give something back.

If you grew up in an open-source environment neither of these are foreign concepts to you.  I don't mean to imply that these are not priorities of yours if you live on the proprietary side of the street but it has been my experience that it may be less likely.  (There is a corollary in there somewhere about folks who are using open-source stuff but not buying into the concept.)

JDeveloper 12c on OS X

First I checked which versions are available with this command:

/usr/libexec/java_home -V

this was the output:
